docs: move the branch's changelog entries into a changelog.d fragment

The Vue and Pinia migration's entries move out of CHANGELOG.md into
changelog.d/0000-vue-and-pinia.md, newest first, as the contributing guide
asks. 0000 stands in for the pull request number until it is opened. The
migration plan's cleanup step now records where it stands: the template
expansion is gone, the pattern is required for new UI, the page-level
markup tests render the real views, the attribute translation pass waits
for vue-i18n, and a host panel registration API waits for its first host.

 ## [Unreleased]
 
-- Each desktop sidebar has an icon rail that lists every panel on that side
-  and opens one with a click. One panel is open per side in every HUD layout,
-  so the collapsed panel headers no longer take up the sidebars. Phones keep
-  the bottom tab bar. The rail is the first view built with Vue and Pinia,
-  which now ship with the app; see docs/VUE-MIGRATION.md (samehkhamis).
-
-- The Authoring, shot list and CCTV buttons and Street Level's nearest button
-  are the kit's `UiButton` (danger buttons in the `alert` tone, primary ones the `primary`
-  variant), keeping their classes; the CCTV on/off, coverage, auto-hop,
-  projection and adjust toggles now say their state with `aria-pressed`
-  (samehkhamis).
-
-- The Data, Authoring, Weather, Recent Imagery, Context, CCTV, Street Level
-  and Radio panels are one component, `UiPanel` (`src/ui/kit/`), with the
-  same markup plus the kit's `ui-panel` classes, their titles translated by
-  `t()` rather than `data-i18n`; `RailPanel` binds it to the panel chrome
-  store. `PanelCollapseButton` drops its `initial` and `initialTitle` props
-  and takes `startCollapsed`, so before startup presents a panel its button
-  already shows that state's glyph, words and `aria-expanded` (samehkhamis).
-
-- The page's panels, dock, cockpit and dialogs are Vue views with the same
-  markup as before. Hosts that do not initialize Core's locale pass
-  `localePicker: false` to `createApplicationControls` to drop the language
-  picker, and Node tests that import application modules register the
-  component loader with `--import=<core>/build/register-vue` (samehkhamis).
-
-- Pages place each view with a `<div class="gev-view" data-gev-view="NAME">`
-  host and write their own loading screen; the `build/html` template
-  expansion and its `gev:template` markers are gone. `createApplication`
-  takes `omitViews` (for example `['provider-settings']`) for views an
-  application leaves out (samehkhamis).
-
-- `./voice/control`'s `createVoiceControl({ panel })` returns the voice
-  control's presenter instead of element handles: owners write it by part
-  (`update('detail', { text })`) and listen with `on('button', fn)`, and the
-  command dock renders it from a store. `createVoiceCommands`' `createControl`
-  and `VoiceCardControls` (`{ ui }` instead of `{ root }`) take the same
-  presenter; the `reset` option is gone, since a newer control replaces the
-  previous one (samehkhamis).
-
-- `./scenes` presents the scene sharing dialogs and the EDIT DETAILS / SHARE
-  SCENE bar through a store that the scene panels view renders, so a page
-  that omits `layer-panels` shows neither (samehkhamis).
-
-- `./ui/display`'s `bindDisplayControls` is gone: the Display panel's
-  controls and the dock's style buttons call their owner through the display
-  store's `connect`/`act`, and its allocation and 3D model choices are the
-  kit's `UiSegmented`. `initDrawTool` takes `connect(actions)`, which returns
-  their disconnect, and no longer listens on the Draw controls; its view
-  publishes `color` and `label` too, and the shape choice is a `UiSegmented`.
-  `initGeoFileImport` takes `connect(actions)` the same way and no longer
-  listens on the Import button, picker or list, nor restores focus itself:
-  the `GeoImport` view does both, and its `publish` need not settle once the
-  list renders. Street Level's fit and panorama filters and Recent Imagery's
-  mode are `UiSegmented` too: the Street Level store's owner answers
-  `setPano` and `setRenderMode`, and `RecentImageryReadout` takes
-  `onSetMode`. The Radio panel's and Cockpit's internet radio controls and
-  the tuner slider's events call `RadioControls`, and the local RTL-SDR
-  card's controls `LocalSdrControls`, through the radio store's new
-  `connect`/`act`; the card labels its gain options itself. `act` returns
-  what the answering action returned. The Display, Radio, RTL-SDR, Cockpit,
-  mission replay, style parameter, rail card, observation timeline, imagery
-  opacity, Street Level date and Bhote Koshi sliders are the kit's
-  `UiSlider`, a native range input that emits numbers, and the pressed
-  toggles are the kit's `UiButton`, which gains `pressedClass`; so are the rail card
-  chips, map source chips and location pills (which now report
-  `aria-pressed`), and the voice card's chips
-  are the kit's new `UiChip`. The selects are the kit's new `UiSelect`, the
-  status badges its new `UiBadge` and the one-line empty states its new
-  `UiEmpty`.
-  The top-center clear, share, tilt, north-up and reset buttons, and the
-  cockpit's reset, call the shell through the new globe actions store,
-  which also carries the camera's tilt and compass heading. The recording
-  safe frame renders what `RecordingControls` publishes to the new
-  recording store. `syncScopeControls` (`./ui/display`),
-  `shouldHideCollapsedRightPanels` (`./ui/layout`),
-  `bindClearLayersControl` (`./ui/layers`) and `createStyleParameters`
-  (`./ui/input`; the Display panel renders the style parameters
-  VisualSettings publishes to the display store) are deprecated: the Display
-  view,
-  the rail and the globe actions view now own what they did. `./ui/input` imports Vue
-  (samehkhamis).
-
-- `./ui/cctv` and `./ui/radio` import Vue and Pinia: their controllers
-  publish the panel's state to a store that the CCTV and Radio views render,
-  instead of writing the panel's markup themselves (samehkhamis).
-
-- `./layers/awareness` no longer writes the Contacts panel into
-  `#military-awareness-panel`: the layer publishes a plain panel view through
-  `subscribePanel(listener)` and Core's Contacts view renders it, calling the
-  layer's `navigatePrevious`, `focusCurrent`, `navigateNext` and `focusTarget`.
-  The `awarenessPanelControlKey`, `captureAwarenessPanelFocus` and
-  `restoreAwarenessPanelFocus` helpers are gone; the view keeps focus itself
-  (samehkhamis).
-
-- `./layers/launches` no longer writes the Space Missions roster or the
-  selected mission panel into `#space-mission-panel-host`: the layer
-  publishes both through `subscribePanel(listener)` and Core's Space Missions
-  views render them, calling the layer's panel commands (`selectMissionAt`,
-  `selectPreviousMission`, `selectNextMission`, `deselectMission`,
-  `focusSelectedLaunchSite`, `startSelectedReplay`, `toggleReplayPause`,
-  `cancelReplay`, `setReplaySpeed` and the `roster*` preview inputs). The
-  `bindMissionRosterItemKeyboardPreview`, `captureMissionRosterFocus` and
-  `restoreMissionRosterFocus` helpers are gone; the roster keeps focus itself
-  (samehkhamis).
-
-- `createMapSourceControls()` (`./ui/maps`) no longer renders the map source
-  chips into a `container` or writes a `statusElement`: it presents the chip
-  row and status badge and hands them to its `publish` option, and Core's
-  dock renders them and calls `select()`. `renderMapStackChips`,
-  `syncMapStackChips` and `MAP_STACK_CHIP_CLASS` are removed (samehkhamis).
-
-- `LocationControls` (`./ui/location`) no longer builds the city and
-  landmark pills or writes the mini status: it presents the tray, including
-  the search error (`setSearchError()`), and hands it to its `publish`
-  option, and Core's dock renders it and calls `chooseCity()` and
-  `choosePoi()`. Its `elements` are now only `search`: `resetButtons` and
-  `searchToggle` are gone, and the reset buttons and the search toggle call
-  its new `reset()` and `toggleSearch()`. It presents the search field's
-  open and searching state too (`searchExpanded`, `searching`; a
-  `searchExpanded` option starts it open), set through `setSearching()`,
-  `settleSearch()` and `closeSearch()`, and a host renders the field's
-  `expanded` and `searching` classes from it; `LocationSearch`
-  takes a `setSearching` option in place of writing the field's class, and
-  `NavigationController` a `settleSearch` option in place of `searchInput`.
-  `createOrbitIndicator()` is replaced by
-  `showOrbit(active)`, which adds the ORBIT indicator to the presented tray
-  as `orbit: { active }` (null until offered) (samehkhamis).
-
-- `IntelHUD` (`./ui/hud`) no longer builds or writes `#intel-hud`: it hands
-  its readouts, visibility, layout variant and style colors to its `publish`
-  option, and Core's `intel-hud` view renders them. A page places that view
-  with `<div class="gev-view" data-gev-view="intel-hud">` instead of a bare
-  `#intel-hud` element. `./layers/vessels` shows the selected vessel's HUD
-  readout through `services.readouts.presentSelectedVessel()` instead of
-  writing `#hud-ais-vessel`; the application passes `src/hudReadouts.js`,
-  which IntelHUD follows (samehkhamis).
-
-- `initFirstRunExperience` (via `./application/chrome`) no longer writes the
-  launcher's classes, attributes or text, or removes the card: it presents
-  them to the welcome view's `gev-first-run` store (its new `store` option)
-  and connects the controls the view's buttons call (samehkhamis).
-
-- `SceneControls` (`./ui/scenes`) no longer takes `elements` or writes the
-  Scene panel's buttons, status, progress or runtime chip: it presents them
-  to the `gev-scenes` store and the panel's buttons call its actions there.
-  `sceneElements`, `presentSceneButtons`, `presentSceneProgress` and
-  `presentSceneRuntime` give way to `sceneButtonsDisabled` and
-  `scenePercent`. It no longer stands down when the page has no Scene
-  panel: ESC still stops a playing scene and the runtime chip still shows
-  (samehkhamis).
-
-- The shell's panel chrome no longer writes the panels' collapse buttons,
-  the dock tray toggles' names or the dock pins' pressed state: it presents
-  each panel's open and pinned state to the `gev-panel-chrome` store, and
-  the buttons, now views, call it there. `bindPanelDisclosure`
-  (`./ui/panels`) binds only a panel's Escape; it no longer takes `buttons`
-  or `onChange`. `UiButton` joins the component kit with ui-vue's props
-  (samehkhamis).
-
-- The panels' own state classes (`collapsed`, `dock-pinned`,
-  `dock-pinned-top`, `layout-auto-collapsed`, `accordion-collapsed`) render
-  from the `gev-panel-chrome` store: the shell, the rails and the accordion
-  present each panel's state there instead of writing its classes.
-  `layoutLeftPanelRail` and `layoutRightPanelRail` (`./ui/layout`) now call
-  `onCollapse(panel, {collapsed, auto})` and leave drawing it to the host. Without a
-  shell to own the panels, the voice tools' `set_panel_open` now reports
-  that there is no panel to open instead of writing its classes
-  (samehkhamis).
-
-- The Cockpit Contact and briefing cards' collapse renders from the
-  `gev-cockpit` store: the controller publishes `contextCollapsed` and
-  `signalCollapsed` in its presence, and each card's `data-collapsed` and
-  its toggle's state, words and icon follow it (samehkhamis).
-
-- The Cockpit utility strip's measured layout renders from the
-  `gev-cockpit` store: the layout pass publishes `utilityLayout` (the HUD's
-  `--cockpit-utility-*` lengths, `primaryOnly` and `hideCollapsed`), and a
-  host constructing `CockpitController` passes `publish.utilityLayout`
-  beside its other publishers (samehkhamis).
-
-- Cockpit's Display popover shows the Display panel's own HUD, Detection,
-  Parameters and 3D groups through Vue teleports: `CockpitDisplayPortal`
-  publishes the popover's slots (`publish`, with `afterRender` to lay out
-  once they have moved) instead of moving the groups itself (samehkhamis).
