M13: anchor manager & friend tags (lane F)

Collapsible #anchor-panel (toggle  #btn-anchors): every anchor gets a color
dot (recolor via inline color input), label (rename via prompt), one-click
jump-to (scene3d.focusOn), and delete — PATCH/DELETE /api/anchors/{id}, then
state.anchors update + emit("anchors-changed") so scene3d + overlays refresh.

+ Tag drives the FROZEN M8 annotator without an event (annotate.js is
null-event safe by construction; the backend keeps event-less annotations as
independent anchors): prompt a name -> startAnnotateMode -> user drags a bbox
on any video -> the resolved anchor is PATCHed to the name + a palette color.
Esc / + Tag again cancels. All mutating controls carry .write-ui (capsule
mode keeps the read-only list + jump). CSS injected from the module —
index.html is frozen.

Live-verified: create->rename->recolor->jump->delete roundtrip, labels in 3D
+ both video overlays, reload survival, capsule hiding (plan/status/lane-F.md).

// Anchor manager & friend tags (spec M13, lane F). STUB — lane F fills THIS FILE ONLY.
// Anchor manager & friend tags (spec M13, lane F).
//
// Pre-wired by foundation2: the hidden ⚓ toggle (#btn-anchors) and the empty #anchor-panel
// container in index.html, this module's import + init() call in main.js, the hooks
// `scene3d.focusOn(x, y, z)` (jump-to) and `PATCH ${state.apiBase}/api/anchors/{id}`
// {label?, color?} (rename/recolor), plus DELETE /api/anchors/{id} from phase 4.
// A collapsible panel (pre-wired container #anchor-panel, toggle #btn-anchors) listing every
// anchor in state.anchors: color dot (recolor), label (rename), jump-to (scene3d.focusOn),
// delete. Mutations go through PATCH/DELETE ${state.apiBase}/api/anchors/{id}; after any
// mutation we update state.anchors and emit("anchors-changed") so scene3d + the video
// overlays refresh (main.js wires that event to scene3d.refreshAnchors; overlays read
// state.anchors every frame).
//
// When implementing: unhide the button, set `ready = true`; build the collapsible list
// (color dot, label, jump-to, rename, recolor, delete) from state.anchors; after any
// mutation update state.anchors and emit("anchors-changed") so scene3d + overlays refresh.
// The Tag flow reuses the M8 bbox-annotation flow WITHOUT an event (annotate.js is
// frozen — drive it, don't edit it) and names the resulting anchor.
// Capsule mode: give every MUTATING control the `write-ui` class — body.capsule hides that
// class globally (contract #5); the read-only list + jump-to stay available.
// Tag (friend tags): drives the FROZEN M8 annotation flow WITHOUT an event.
// annotate.js was written null-event safe on purpose: startAnnotateMode() only needs the
// registered cells, and _submit POSTs /api/annotations with event_id: null, which the backend
// resolves to an INDEPENDENT anchor ("Annotations with no event stay independent").
// Flow: prompt for the friend's name -> annotator.close() (clears any currentEvent) ->
// annotator.startAnnotateMode() -> the user drags a bbox over the friend on any video ->
// the resolved anchor arrives via emit("anchors-changed", anchor) -> we PATCH the pending
// name + a palette color onto it and stop annotate mode. Esc (or Tag again) cancels.
//
// Capsule mode (contract #5): every MUTATING control carries class="write-ui" so a baked
// bundle hides it; the read-only list + jump-to stay available.
