Separates the Claude-specific daemon (idle timer, tmux pane detection,
prompt injection, RPC server, session hooks) from the universal
infrastructure (channels, supervisor, notify, daemon protocol).
thalamus/ now contains only substrate-independent code: the channel
client/supervisor, notification system, daemon_capnp protocol, and
shared helpers (now(), home()).
claude/ contains: idle.rs, tmux.rs, context.rs, rpc.rs, config.rs,
hook.rs (moved from subconscious/), plus the daemon CLI and server
startup code from thalamus/mod.rs.
All re-exports preserved for backward compatibility.
