refactor(effect): unify service namespaces for file, format, vcs, skill, snapshot

Collapse the two-namespace pattern (e.g. File + FileService) into a single
namespace per module: Interface, Service, layer, and defaultLayer all live on
the domain namespace directly. Rename DiscoveryService → Discovery for
consistency. Remove no-op init() methods and unnecessary defaultLayer = layer
re-exports per EFFECT_MIGRATION_PLAN.md conventions.

 - These helpers use the fixture-enabled test-only terminal driver and wait for output after the terminal writer settles.
+- After opening the terminal, use `waitTerminalFocusIdle(...)` before the next keyboard action when prompt focus or keyboard routing matters.

 - Keep these hooks minimal and purpose-built, following the style of `packages/app/src/testing/terminal.ts`
 - Test-only hooks must be inert unless explicitly enabled; do not add normal-runtime listeners, reactive subscriptions, or per-update allocations for e2e ceremony
 - When mocking routes or APIs, expose explicit mock state and wait on that before asserting post-action UI
+- Add minimal test-only probes for semantic state like the active list item or selected command when DOM intermediates are unstable
+- Prefer probing committed app state over asserting on transient highlight, visibility, or animation states
 
 ### Prefer helpers
 
 - Prefer fluent helpers and drivers when they make intent obvious and reduce locator-heavy noise
 - Use direct locators when the interaction is simple and a helper would not add clarity
+- Prefer helpers that both perform an action and verify the app consumed it
+- Avoid composing helpers redundantly when one already includes the other or already waits for the resulting state
+- If a helper already covers the required wait or verification, use it directly instead of layering extra clicks, keypresses, or assertions

 ## Errors
 
 - In `Effect.gen/fn`, prefer `yield* new MyError(...)` over `yield* Effect.fail(new MyError(...))` for direct early-failure branches.
+
+## Instance-scoped Effect services
+
+Services that need per-directory lifecycle (created/destroyed per instance) go through the `Instances` LayerMap:
+
+1. Define a `ServiceMap.Service` with a `static readonly layer` (see `FileWatcherService`, `QuestionService`, `PermissionService`, `ProviderAuthService`).
+2. Add it to `InstanceServices` union and `Layer.mergeAll(...)` in `src/effect/instances.ts`.
+3. Use `InstanceContext` inside the layer to read `directory` and `project` instead of `Instance.*` globals.
+4. Call from legacy code via `runPromiseInstance(MyService.use((s) => s.method()))`.
+
+### Instance.bind — ALS context for native callbacks
+
+`Instance.bind(fn)` captures the current Instance AsyncLocalStorage context and returns a wrapper that restores it synchronously when called.
+
+**Use it** when passing callbacks to native C/C++ addons (`@parcel/watcher`, `node-pty`, native `fs.watch`, etc.) that need to call `Bus.publish`, `Instance.state()`, or anything that reads `Instance.directory`.
+
+**Don't need it** for `setTimeout`, `Promise.then`, `EventEmitter.on`, or Effect fibers — Node.js ALS propagates through those automatically.
+
+```typescript
+// Native addon callback — needs Instance.bind
+const cb = Instance.bind((err, evts) => {
+  Bus.publish(MyEvent, { ... })
+})
+nativeAddon.subscribe(dir, cb)
+```
+
+## Flag → Effect.Config migration
+
+Flags in `src/flag/flag.ts` are being migrated from static `truthy(...)` reads to `Config.boolean(...).pipe(Config.withDefault(false))` as their consumers get effectified.
+
+- Effectful flags return `Config<boolean>` and are read with `yield*` inside `Effect.gen`.
+- The default `ConfigProvider` reads from `process.env`, so env vars keep working.
+- Tests can override via `ConfigProvider.layer(ConfigProvider.fromUnknown({ ... }))`.
+- Keep all flags in `flag.ts` as the single registry — just change the implementation from `truthy()` to `Config.boolean()` when the consumer moves to Effect.
