JinjingandOrca e7703a772b fix(terminal): bound hidden-worktree retention with a force-park budget (C1, slice B)
Un-parkable worktrees (remote-runtime ptys, uncoverable tabs, SSH with the
slice-A switch off) had unlimited retention: the parking cap/TTL only ever
saw eligibility-passing worktrees, so one bad tab pinned a whole worktree's
panes forever. Retention is now memory-bounded, not eligibility-bounded.

- terminal-hidden-worktree-retention.ts: retention budget (12 hidden / 45min
  TTL, sized from the measured 2.5-19MB per-pane V8 cost, DESIGN.md §2) over
  hidden worktrees ordinary parking can never evict; reuses the hot-retain
  ranking so last-active exemption, deterministic ties, and deadline-driven
  rechecks hold. Fail-open/foreign-pty tabs are eviction-exempt (a remount
  would fresh-spawn and orphan the live shell).
- Terminal.tsx: force-parked ids join the parked set AFTER the coverage veto
  (darkness for uncoverable tabs is the accepted cost); buffers captured via
  the sleep-flow registry before the unmount render; retention TTL added to
  the recheck deadlines for budget candidates only.
- Verdict stays out of its own effect deps; policy test asserts idempotence
  and time-monotone membership (flip-loop dwell regression).
- Kill switch: settings.terminalHiddenWorktreeRetentionBudget (default on).
