4608665e82 refactor: Implement 2-container architecture to solve USB stability issues 
BREAKING CHANGE: Switched from single-container to multi-container setup

This commit introduces a meshcore-bridge service that isolates USB device
access from the main application, resolving persistent USB timeout and
deadlock issues in Docker + VM environments.

Changes:
- Add meshcore-bridge/ - Lightweight HTTP API wrapper for meshcli
  - Flask server exposes /cli endpoint (port 5001, internal only)
  - Exclusive USB device access via --device flag
  - Health check endpoint at /health

- Refactor app/meshcore/cli.py
  - Replace subprocess calls with HTTP requests to bridge
  - Add requests library dependency
  - Better error handling for bridge communication

- Update docker-compose.yml
  - Define meshcore-bridge and mc-webui services
  - Create meshcore-net Docker network
  - Add depends_on with health check condition
  - Bridge gets USB device, main app uses HTTP only

- Modify Dockerfile
  - Remove meshcore-cli installation from main app
  - Lighter image without gcc dependencies

- Update config.py
  - Add MC_BRIDGE_URL environment variable
  - Remove meshcli_command property (no longer needed)

- Update documentation (README.md, .claude/instructions.md)
  - Document 2-container architecture
  - Add troubleshooting section for bridge
  - Update prerequisites (no host meshcore-cli needed)
  - Add architecture diagram in project structure

Benefits:
✅ Solves USB device locking after container restarts
✅ Restartable main app without USB reset
✅ Better separation of concerns
✅ Easier debugging (isolated meshcli logs)
✅ No manual USB recovery scripts needed

761e4eac25 feat: Implement full channel management functionality 
Add comprehensive channel management features to mc-webui:
- Create new channels with auto-generated encryption keys
- Share channels via QR code or copy-to-clipboard
- Join existing channels with name and key
- Switch between channels in chat interface
- Filter messages by channel
- Persistent channel selection (localStorage)

Backend changes:
- Add CLI wrapper functions: get_channels, add_channel, set_channel, remove_channel
- Modify send_message() to support channel targeting
- Parametrize parser channel filtering (channel_idx parameter)
- Add QR code generation with qrcode + Pillow libraries

API endpoints:
- GET /api/channels - List all channels
- POST /api/channels - Create new channel
- POST /api/channels/join - Join existing channel (auto-detect free slot)
- DELETE /api/channels/<index> - Remove channel
- GET /api/channels/<index>/qr - Generate QR code (JSON or PNG)
- Modified GET /api/messages - Add channel_idx filtering
- Modified POST /api/messages - Add channel_idx targeting

Frontend changes:
- Add channel selector dropdown in navbar
- Add Channels Management modal (create, join, list)
- Add Share Channel modal (QR code, copy key)
- Implement JavaScript channel management logic
- Add event handlers for channel switching
- Persist selected channel in localStorage

QR code format:
{"type":"meshcore_channel","name":"...","key":"..."}

Protection:
- Block deletion of Public channel (index 0)
- Validate channel names (alphanumeric, _, - only)
- Validate encryption keys (32 hex chars)
- Auto-detect free channel slots (1-7)

Backward compatibility:
- Default channel_idx=0 (Public) in all functions
- Existing Public-only code continues to work
