hcmHandleBlocked no longer re-checks local control mode before acting. Background
only sends HOST_BLOCKED to a gated guest, so the message itself is authoritative —
adopt host-only/guest role from it. Fixes the join race where a HOST_BLOCKED
arriving before the CONTROL_MODE broadcast was silently ignored.
Also corrects the EC-4 note: "let catch-up re-sync" is invalid (sync is
event-driven, no continuous catch-up); the right fix is a buffer-aware deferred
snap-back.

- popup: lock remote-control buttons (Play/Pause/SYNC) for guests in host-only
mode so clicks don't silently get gated and leave the button stuck; backstop
guards in the handlers and the 2.5s safety reset respects the lock.
- content: rebuild the desync dialog + resync badge with the DOM API inside a
Shadow DOM. innerHTML inline style="" attributes are stripped by strict
style-src CSP (Netflix/YouTube/Disney+); CSSOM .style is CSP-safe and the
shadow root isolates from page CSS.
- content: detect live-DVR in hcmIsLive() via a sliding seekable window
(seekable.start(0) > 1), not just duration === Infinity (EC-15).
Records remaining audit items (snap-back thrash, join race, dialog i18n) in the
edge-case log for the device-testing pass.

All five layers implemented; automated checks green. Records what still needs
real-device testing (EC matrix) and what was deferred by decision.

Step 1 of host control mode. Adds the protocol surface only — no behavior yet:
- EVENTS.SET_CONTROL_MODE (client->server: host sets mode)
- EVENTS.CONTROL_MODE (server->client: mode changed)
- CONTROL_MODES { EVERYONE, HOST_ONLY }
Purely additive; old clients ignore the new events. Propagated to
extension/shared via build-extension. Also records the audited design
decisions in the edge-case log.

Planning docs for the optional per-room Host Control Mode (Teleparty-style
host-only playback control) requested via GitHub issue.
- host-control-mode-EDGECASES.md: canonical branch entry-point — goals, scope,
trust model, architecture summary, 21 edge cases, test matrix, open decisions.
- host-control-mode-plan.md: layered implementation plan with concrete code hooks
(server room state, three-layer gate, snap-back, guest desync flow, UI/i18n).
Temporary working docs for this branch; to be folded in or removed before merge.
