EnsureExists blindly seeded ~/.todo-app/prompts/*.md with the bundled
default and never revisited it, so any file created by opening the
Files settings tab shadowed every later default change permanently
(SuggestImprovement/AskUser sections never reached real runs since
2026-06-04). PromptFiles now hashes what a file was seeded/saved with
in prompts/.defaults.json: Classify() tells missing/current-default/
known-past-default/edited apart, ReconcileStaleDefaults() drops files
that only ever matched a superseded default, and real edits are left
alone and surfaced in the Files tab with a diff + reset-to-default
action. QuarantineOrphans() moves stale-named leftovers (agent.md,
planning.md) into prompts/_orphans instead of silently deleting them.
Wired as a Worker startup sweep (PromptFileRecovery) alongside the
existing OrphanRecovery/AttachmentOrphanRecovery services.
Add 16 missing members to IWorkerClient (IsReconnecting, WorkerLogReceivedEvent,
PrimeFired, LastApproveTarget, Refresh/RestoreDefaultAgents, UpdateAppSettings,
prime schedule CRUD, UpdateList/UpdateListConfig, all worktree ops).
Switch all production consumers off the concrete WorkerClient type; only
Program.cs/App host still resolves the concrete registration.
Update StubWorkerClient and FakeWorkerClient to satisfy the expanded interface.
