TheoChat v1.4.2

TheoChat v1.4.2 — Real-time moderation

Removes the mandatory 30-second chat delay that v1.3.0 introduced. YouTube messages
now render into Twitch chat in ~100-200ms instead of being held for half a minute.

Changed

• Messages render immediately. The 30s pre-render hold is gone. Mod delete and
  ban events continue to remove messages in real time via gRPC tombstones.
• Popup redesign. The disabled-slider "MOD SAFETY WINDOW" section is now a
  static "DELIVERY MODE: LIVE" readout. The BUFFERED telemetry cell is now MODE.

Removed

• DEFAULT_DELAY_MS, MIN_SAFE_DELAY_MS, DELAY_MS constants in content.js
• pendingQueue, queueOrInject(), flushPendingQueue()
• theochat.setDelay message handler
• Delay slider in popup.html

Rationale

The 30s buffer was a defensive workaround that duplicated what gRPC tombstones
already solve. The real-time tombstone path delivers mod deletions in ~50-200ms,
and the existing reconcile sweep catches anything missed. The forced 30s hold
just made Twitch viewers see YouTube chat half a minute late with no added
moderation safety.
