Small pill in bottom-right corner of every page: "● gstack · 3 refs"
Shows when connected via CDP, fades to 30% opacity after 3s, full on hover.
Disappears entirely when disconnected.
Background worker now notifies content scripts on connect/disconnect state
changes so the pill appears/disappears without polling.

Chrome extension (Manifest V3, sideload):
- Side Panel with live activity feed, @ref overlays, dark terminal aesthetic
- Background worker: health polling, SSE relay, ref fetching
- Popup: port config, connection status, side panel launcher
- Content script: floating ref panel with @ref badges
Conductor API proposal (docs/designs/CONDUCTOR_SESSION_API.md):
- SSE endpoint for full Claude Code session mirroring in Side Panel
- Discovery via HTTP endpoint (not filesystem — extensions can't read files)
TODOS.md: add $B watch, multi-agent tabs, cross-platform CDP, Web Store publishing.
Mark CDP mode as shipped.
