Three independent reliability fixes that all surfaced as the same bug:
live tasks losing their worktrees mid-execution and emitting
`wrong_toplevel` errors.
Fix A — executor stale-self-owned classifier:
`reconcileSelfOwnedActiveSessionForRemoval` now takes a process-active
probe (`executingTaskLock.has`) and a minimum-idle window (default 5s)
in addition to the existing in-memory `activeWorktrees` binding probe.
Recently-registered or still-running entries are refused with
`process-active-refuses` / `too-recent-refuses`, with audit-grade
log lines. Both the pre-remove path
(`reconcileSelfOwnedBeforeRemove`), the post-throw retry in
`removeOwnWorktreeWithReconcile`, and the defensive reconcile in
`removeWorktree` route through the same hardened gates.
Fix B — pause synchronously reaps the agent session:
New `awaitAbortInFlightTaskWork` mirrors the existing fire-and-forget
abort but awaits each `session.abort()` /
`stepExecutor.terminateAllSessions()` /
`workflowSession.abort()`. `parkTaskAfterWorkflowStepPause` calls it
before `moveTask("todo")`, and the `task:updated` user-pause handler
routes through it, so a fast re-dispatch can no longer race a still-
live shell.
Fix C — self-healing realpath + active-task skip:
`reconcileTaskWorktreeMetadata` now realpath-normalizes both sides of
the registry comparison (handling macOS `/private/var/...`) and
refuses to clear `worktree`/`branch` on in-progress or in-review
tasks. The skip emits a new
`task:auto-recover-worktree-metadata-skipped-active` audit event;
executor-level recovery paths remain in charge of active tasks.

The merge replaces all real `setTimeout`/`sleep` polling with deterministic event-based waits across the executor pause integration tests, restart integration tests, dashboard tests, and chat-store tests, making the suite faster and more reliable.

Adds test coverage for task environment propagation through the spawn flow, covering child agents inheriting task env, workflow step task env, and spawn hook env isolation cases in `pi-create-fn-agent.test.ts`, with minor additions to `executor-step-session.test.ts` and `executor-pause.test.ts`.

The merge splits the large monolithic `executor.test.ts` into seven focused test suites covering core logic, pause behavior, prompt handling, recovery, review verdicts, step sessions, and worktree operations, and adds shell context hook plumbing across the dashboard, desktop, and mobile packages to
