/**
 * schedule-store.ts — File-backed store for scheduled subagents.
 *
 * Session-scoped: each pi session owns its own schedules at
 * `<cwd>/.pi/subagent-schedules/<sessionId>.json`. `/new` starts a fresh
 * empty store; `/resume` reloads.
 *
 * Concurrency model lifted from pi-chonky-tasks/src/task-store.ts: every
 * mutation acquires a PID-based exclusion lock, re-reads the latest state
 * from disk, applies the change, atomic-writes via temp+rename, releases.
