fix: remove context reaper to prevent background tabs from going stale

Background windows stopped updating because the reaper suspended contexts
after ContextSuspendAfter and fully reaped them after ContextTTL. Suspended
contexts had to re-run the page init function from scratch on reconnect,
losing the live-updating experience.

Contexts now live until the browser tab closes (beforeunload beacon) or
the server shuts down. The context map grows indefinitely — no background
reaper.

Removes: startReaper, reapOrphanedContexts, suspend/resume logic,
ContextSuspendAfter/ContextTTL config fields, lastSeenAt/suspended
context fields, and all associated tests.

 6. Wait for CI to pass: poll Gitea CI status. If CI fails, report the failure and stop — do not merge.
 7. Once CI passes, squash-merge on Gitea: `tea pr merge <index> --style squash` with a clean, semantic commit message including the PR number. No Claude attribution lines.

If in a worktree, `main` is checked out in the primary tree, so run from there: `cd <primary-worktree> && git pull gitea main && git push origin main` (the primary worktree path is the repo root without `.claude/worktrees/…`).
