channel architecture: wire protocol, daemons, supervisor
Design and implement the channel system for external communications:
- schema/channel.capnp: wire protocol for channel daemons
(recv with all_new/min_count, send, subscribe, list)
- channels/irc/: standalone IRC daemon crate (consciousness-channel-irc)
- channels/telegram/: standalone Telegram daemon crate
(consciousness-channel-telegram)
- src/thalamus/channels.rs: client connecting to daemon sockets
- src/thalamus/supervisor.rs: daemon lifecycle with file locking
for multi-instance safety
Channel daemons listen on ~/.consciousness/channels/*.sock,
configs in *.json5, supervisor discovers and starts them.
IRC/Telegram modules removed from thalamus core — they're
now independent daemons that survive consciousness restarts.
Also: delete standalone tui.rs (moved to consciousness F4/F5),
fix build warnings, add F5 thalamus screen with channel status.
