Merge upstream/main (v0.2.1) into pr/mapillary-layer

Brings in 123 commits from main, including the v0.2.0 and v0.2.1 releases
(MCP server and tool catalog, server security hardening, build hygiene).

Conflicts:
- package.json: kept main's script order and added this PR's
  qa:panel-resize and qa:street-level; exports keep both sides (main's
  tools/view entries and this PR's street-level and Mapillary entries).
- src/tooling/viteBuild.test.mjs: kept this PR's Mapillary-token define
  assertion and main's new wildcard-host allowedHosts assertions.
- CHANGELOG.md: main now has release sections; this PR's entries go under
  [Unreleased].

Checks after the merge: doctor, format:check, check:boundaries,
layer-token:check (28 published, 1 new: street-level 0), npm test (5726
pass), build, the Windows job's focused tests (70 pass), qa:panel-resize,
and the keyless street-level gate. The new CSP allows Mapillary (https:
connect/img, blob workers). The keyed gate stops at coverage locally
because the dev .env Mapillary token is invalid (upstream 403), not because
of the merge.

-By default nobody else can reach your server — it binds to localhost. To share on your LAN, opt in explicitly (`npm run dev -- --host 0.0.0.0 --port 4173`, or `HOST=0.0.0.0 ./scripts/dev-fresh.sh` on macOS/Linux) — but know that ⚠️ **a LAN-visible server brokers your configured API keys to anyone who can reach it.** Set the per-IP throttles (`GEV_RATELIMIT_OPENAI_PER_MIN`, `GEV_RATELIMIT_GOOGLE_PER_MIN` — see `.env.example`) and, before anything else, **configure provider quotas, usage limits, and billing alerts**: app-level throttles are not billing caps, and a budget alert alone does not stop spending.

+By default nobody else can reach your server — it binds to localhost. To share on your LAN, opt in explicitly (`npm run dev -- --host 0.0.0.0 --port 4173`, or `HOST=0.0.0.0 ./scripts/dev-fresh.sh` on macOS/Linux). IP addresses work as they are; if you use a LAN hostname, add it with `GEV_ALLOWED_HOSTS=globe.lan`, since binding to `0.0.0.0` does not trust arbitrary Host headers. But know that ⚠️ **a LAN-visible server brokers your configured API keys to anyone who can reach it.** Per-IP throttles on the cost-bearing endpoints are on by default (`GEV_RATELIMIT_OPENAI_PER_MIN`, `GEV_RATELIMIT_GOOGLE_PER_MIN` — see `.env.example` to tune them), but before anything else, **configure provider quotas, usage limits, and billing alerts**: app-level throttles are not billing caps, and a budget alert alone does not stop spending.

 Provider Settings is disabled when the server is shared, so remote users cannot
 access the key-entry panel.
