The live `agentStatusByPaneKey` map had no size cap. `setAgentStatus` rewrites it with a full spread copy on every status ping and keeps rows until a pane/tab teardown event removes them; a missed teardown (agent killed without a Stop hook, pane/tab closed while its status lingered) orphans a row forever. On long multi-agent sessions orphaned heavy rows accumulate without bound, and because each ping spread-copies the whole map, once it is ~1.9 GB one ping transiently doubles it past the 3586 MB old-space limit -> renderer crash (exit -36861). Cap the live map at MAX_LIVE_AGENT_STATUSES=500, shedding only rows whose pane is provably gone (a mounted tab's rooted layout no longer lists the leaf) or long idle, and never an open pane's row (any state, incl. needs-input waiting/blocked). Rootless/empty-snapshot, not-yet-hydrated, and no-renderer-tab (orchestration worker) rows are unprovable: kept while a fresh agent could own them, shed only past the stale window or by a hard-cap fallback that guarantees the bound. Eviction bumps the status/sort epochs so the retention sync snapshots disappeared done rows. Cost is one Object.keys length check on the reducer's already-O(n) spread under the cap; the layout walk + sweeps run only on the rare over-cap ping.

Features
Also in the box:
- Quick open — Search across worktrees, files, agents, commands, and repo context without leaving your flow.
- Account switcher & usage tracking — See Claude and Codex usage and rate-limit resets, and hot-swap accounts without re-logging in.
