feat(phase6): docs, lint fixes, STATE.json update

- Fix lint errors in plugin-client.js (unused var, empty block)
- Update README with plugin architecture and env vars
- Update STATE.json to v4.1 IMPLEMENTATION_COMPLETE
- All 96 tests passing, 0 lint errors

 ## Architecture
 
+Two rendering modes (auto-detected):
+
+### Plugin Mode (preferred)
+When the Mattermost plugin is installed, updates stream via WebSocket:
+- Custom post type `custom_livestatus` with terminal-style React rendering
+- Zero Mattermost post API calls during streaming (no "(edited)" label)
+- Auto-scroll, collapsible sub-agents, theme-compatible
+
+### REST API Fallback
+When the plugin is unavailable, updates use the Mattermost REST API:
+- Blockquote-formatted posts updated via PUT
+- Shows "(edited)" label (Mattermost API limitation)
+
