refactor: add shared TTL memo reset registry

[thymikee]

Summary

Add a shared TTL memo helper with a process-memo reset registry wired into Vitest setup, so registered process-global memos clear after each unit/provider test by construction.

Migrate the simulator booted memo, daemon device-ready cache, and Apple tool fingerprint cache off ad hoc test reset exports while preserving their cache keys and TTL/process-lifetime behavior.

Add focused coverage for TTL expiry, scheduled expiry, registry-backed cross-test cleanup, and a migrated simulator boot memo leak scenario. Closes #1042.

Touched files: 11.

Validation

Passed: pnpm exec vitest run src/utils/__tests__/ttl-memo.test.ts src/platforms/apple/core/__tests__/simulator-booted-memo.test.ts src/daemon/__tests__/device-ready.test.ts src/platforms/apple/core/__tests__/runner-xctestrun.test.ts --project unit.

Passed: pnpm check:quick.

Passed after building dist: pnpm build, then pnpm test:smoke.

Residual risk: exact pnpm check:unit was run twice but did not pass in this local environment. The failures were nondeterministic across runs, mostly full-suite timeouts or mocked adb/xcrun helper misses in unrelated files; the failed files I reran in isolation passed.

Review: LGTM. The API is right-sized (lazy expiry on get, opt-in scheduled expiry with unref'd timers — checked, line 55), the vitest global afterEach reset via setupFiles kills the leak class by construction, and the acceptance bar from #1042 is met: zero __reset*ForTests exports remain outside the registry (grepped), and the three named memos migrated. 422 tests across the touched suites + typecheck green locally. This retires the bug class that fired three times last week.

Review pass: no actionable blockers found. This satisfies #1042 by introducing a shared TTL memo plus a process-level reset registry wired into unit/provider setup, and it migrates the simulator boot memo, device-ready cache, and Apple tool fingerprint cache without changing their production cache keys/TTL behavior. The sequential leak tests cover registry cleanup, and CI is green. I marked this ready-for-human. Residual note: the worker reported local full-suite check:unit flake, but the PR head Unit Tests/Coverage/Integration and smoke jobs are passing in CI.
