split idle state: thalamus (universal) + claude (tmux wrapper)

Browse source 
thalamus/idle.rs: pure state machine — activity tracking, EWMA,
timers, sleep/quiet/dream state, notifications. No tmux, no
Claude Code dependencies.

claude/idle.rs: wraps thalamus state via Deref, adds claude_pane
tracking, tmux prompt injection, dream nudges, context building.
The Claude-specific tick() loop stays here.

The consciousness binary can now use thalamus::idle::State directly,
fed by TUI key events instead of tmux pane scraping.
