Input history is now a single global ring (recordInput) shared by every input surface —
free-chat, the workflow-intent line, and in-session chat — so ↑/↓ recalls anything you've
sent, including outside a session (previously per-session, so idle/intent had none).
Copy fix: the 120ms animation tick now only runs while something actually animates
(animating(): active session spinner, blinking caret, reconnect). Init no longer starts it
unconditionally; tickKick (re)starts it on demand and tickMsg stops it when idle. An idle
screen no longer auto-redraws, so a native terminal text selection survives instead of being
wiped every frame. Tests cover the ring (dedup/cap/cross-context walk) and the idle gate.
