feat(weather): add globe wind, observed weather and cyclone context (#617)

Wind (NOAA GFS and ECMWF IFS: animated particles, colour field, a reading at map centre), observed weather (NOAA MRMS radar, GOES and NESDIS infrared clouds, lightning density) on one shared history timeline, NHC and CPHC cyclone advisories with tracks and cones, and a WEATHER panel in the right rail. On 3D Tiles the observed products render as raised shells with a sharper window around the view.

+### Adding a right-rail readout panel
+
+Add the shell in `src/ui/templates/context.html` inside `#right-context-rail`:
+a `.panel-collapsible` with a stable `id` and matching `data-panel-id`, the
+existing `.panel-header`, collapse button and a dedicated body. Register it
+with the existing panel chrome/layout owners; do not allocate rail space in
+the body renderer. Set `hidden` while empty so the allocator ignores it, and
+expand through the existing collapse button only on first appearance per page
+session, and only when the chrome marked the restored state as a default
+(`data-collapsed-preference`), never over a stored or shared choice. Preserve
+the user's later collapse choice, including body remounts. Mark the body
+`data-rail-scroller` when it scrolls: the rail's measuring pass lifts its
+`max-height` and puts the scroll offset back afterwards. Panel bodies only
+scroll on an open-card change, with one write, never on a refresh.
+
+Compose `createRailCards({ container, document, onParams, onOpen })` and
+`createRailTimeline({ container, document, onCommit, onPreview, onStep,
+onLatest, onPlay })`. Cards reconcile `{ id, title, badge, open, compact,
+compactStatus, blocks }` in place. Their full-width native button headers expose
+`aria-expanded` and `aria-controls`; articles expose `data-open`. The feature
+adapter owns accordion state. Generic cards do not select data or enable layers.
+
+`blocks` is an ordered array of loose, optional `{ id, type, ... }` descriptors,
+rendered by `railCardBlocks.js`. There are no per-section disclosures:
+
+- `summary`: `text`, a single summary line.
+- `list`: `list: { ariaLabel, items }`, reconciled by `syncRowList` in `rowList.js`.
+- `lines`: keyed `lines: [{ id, text, muted? }]` for details and status.
+- `settings`: `settings: [{ id, label, chips }]`; each labelled row has a 56 px
+  label column and a wrapping `syncChipGroup` from `chipGroup.js`.
+- `legend`: `legend: { colors, labels, units?, zeroIndex?, categorical? }` for a
+  ramp/scale (including a physical freezing anchor) or separate keyed swatches.
+- `actions`: keyed `actions: [{ id, label, params?, href?, onClick?, disabled?,
+hint? }]` in a footer, using buttons or safe new-tab links.
+- `result`: `label`, keyed `lines`, and optional `clear: { params | onClick }`;
+  its accessible × button sits beside the title.
+
+Every block and control has a stable id. Lists, settings, actions and results
+can appear in any requested order, including a scene panel's rectangle action,
+results list, then selected-scene details. Chip/list/action `params` dispatch
+through `onParams(cardId, params)`; the feature adapter supplies
+`setLayerParams(id, params, { origin: 'user' })`. Current descriptors and disabled
+state are read at dispatch. Identical updates do not move nodes or write DOM;
+focused controls survive feed refreshes.
+
+Weather descriptors retain top-level `chips`, `list` and `legend` for non-DOM
+consumers. They expose `summary.settings`, `summary.actions` and optional
+`summary.result`; wind also retains its raw captured `summary.reading`.
+`readout: true` layer rows render only the toggle and source/meta line; their
+subscriptions still refresh the cards. Cards own configuration and readings.
+
+Weather orders cyclones, wind, then a bordered Observed history group containing
+the timeline and active radar, satellite and lightning cards. The group heading
+and scope name its active products. The timeline stays visible whenever any
+observed product is enabled; fewer than two ticks disables transport. Pass
+`heading: false` to the timeline when the containing group owns the heading.
+Exactly one active card is open. Header clicks and newly enabled ids choose it
+(the last new entry wins a batch); refreshes and clock ticks retain it. First
+appearance uses cyclones with storms, otherwise the first card. Disabling the
+open layer falls back to the first remaining card. A WeakMap per document keeps
+explicit choices through body remounts without adding share state. Card opening,
+storm selection and layer enabling remain independent.
+
+Optional card/badge/slider class names provide feature styling. Card titles use
+`.data-name` typography; meta/time/badges use `.data-toggle-meta` typography;
+setting/result labels use `.panel-title`; chips retain `.data-toggle-chip`.
+Reserve one status line, even without a legend. Use app tokens. Wind's footer
+reads the map center into a result after the action. The captured location stays
+fixed until another read; model changes resample that location, units reformat
+it, and × clears both reading and map marker.
+
+The timeline shows endpoint times and receives ticks, index, mode, playing,
+readout and disabled state. Its preview callback receives the tick and index and
+may return readout text; commits receive the same values after a 150 ms coalesced
+drag or final change. Feature adapters own data mapping and service subscriptions;
+generic modules own DOM/listeners/timers and release them in `destroy()`.
+
+Keep persistence with panel chrome: collapse uses
+`godsEyeView.v6.panelCollapsed.<panelId>`, position uses
+`godsEyeView.v8.panelPos.<panelId>`, and share state uses the registered panel id.
+Do not rename existing
+ids or reset persistence versions when adding a body. The WEATHER adapter is
+`src/ui/weatherPanel.js`; its observed-history selection remains transient.
