- Fix metadata flow: store sender_phone for response routing
- Add credential injection in headers (Bearer {WHATSAPP_ACCESS_TOKEN})
- Add secret_validated check for webhook defense in depth
- Add status message filtering to prevent loops
- Add proper WhatsApp API error response parsing
- Create whatsapp.capabilities.json with setup/secrets/rate limits
- Add docs/BUILDING_CHANNELS.md with patterns and examples
Also fix UTF-8 truncation bugs across codebase:
- wrapper.rs: content preview, response body, webhook body logging
- agent_loop.rs: params truncation for approval display
- shell.rs: truncate_for_error() helper
