* refactor: collapse public Platform ios/macos into apple (#979)

Phase 3 d.3: collapse the internal `Platform` union from `ios`/`macos` to a
single `apple` platform, with `appleOs` as the sole OS discriminant. Approach
(b) NON-BREAKING: the daemon still ACCEPTS the legacy `ios`/`macos` selectors on
every read path and still EMITS the leaf `ios`/`macos` strings on every output,
so machine consumers see no change.

Kernel (src/kernel/device.ts):
- PLATFORMS = ['apple','android','linux','web']; add PUBLIC_PLATFORMS (leaf) and
  PublicPlatform; PLATFORM_SELECTORS keeps legacy `ios`/`macos` as input aliases.
- New predicates: isMacOs (appleOs- or legacy-leaf-based), isIosFamily (the
  post-collapse equivalent of `platform === 'ios'`), publicPlatformString (output
  projection), deviceFieldsFromPublicPlatform (inverse), isPublicPlatform.
- isMobilePlatform and matchesPlatformSelector are now device-aware (appleOs).

Discovery now stamps `platform: 'apple'` (+ appleOs); ~125 internal
`device.platform === 'ios'|'macos'` branch sites migrated to the predicates,
behavior-preserving. Apple plugin owns `['apple']`; platformDescriptors collapse
to one `apple` row.

Output projection (approach b) emits the leaf via publicPlatformString at:
devices / session_list (session-inventory), boot / shutdown / appstate /
prepare-ios-runner (session-state, session), the selector/backend platform
(selector-runtime/screenshot-runtime/snapshot-runtime/interaction-runtime),
proxy device key, request-lock backfill, runtime-set binding, click-button
validation, and both `.ad` context-line writers.

Contracts/client keep leaf types (PublicPlatform); read paths (parsePlatform,
REPLAY_METADATA_PLATFORMS, matchesPlatformSelector) accept `apple` + legacy
leaves. Adds a parity test gate (platform-collapse-parity.test.ts).

Refs #979 (part of #972).

* fix: project platform to the public leaf at open/perf response sites (#979)

The Platform collapse left two daemon response builders emitting the raw
internal `device.platform` ('apple'), which the client normalizer rejects
(isPublicPlatform excludes 'apple') — dropping the resolved device from the
response:
- session-open-surface.ts: `open` result `platform`/device projection.
- session-perf.ts: the perf/frames/memory base response builders.
Both now go through `publicPlatformString(device)`, so output stays the leaf
`ios`/`macos` per approach (b). (The android/non-apple perf branches were
already leaf-safe.)

Also update macos-desktop provider test: the lifecycle mock observes the
INTERNAL DeviceInfo, which is now `platform:'apple'` (+ appleOs:'macos'), so the
recorded tag is `prepare:apple:desktop`.

Fixes the provider-integration assertions that blocked both the Integration
Tests and Coverage CI jobs (both run the provider-integration project).
Verified: provider-integration 82/82, coverage passes, tsc/oxlint/oxfmt/layering/
fallow green.

* fix: project platform to the public leaf at nested output sites (#979)

The Platform collapse (approach b) projects device.platform through
publicPlatformString at emit sites so machine consumers keep seeing the
leaf ios/macos and never the internal `apple`. Several nested output
fields were missed. Project them and narrow their emitted types to
PublicPlatform:

- Apple perf memory snapshot support (buildAppleMemorySnapshotSupport) —
  response.support.platform / artifact.support.platform, plus the
  sibling sampleAppleFramePerf error data.
- Apple xctrace perf capture/result platform surfaced in the perf
  cpu-profile started/stopped response data.
- snapshotDiagnostics.stats.platform (recordSnapshotTiming) surfaced in
  snapshot/test response data and the slow-snapshot warning string.
- doctor target-app evidence.platform + human summary, and doctor
  target-app-device evidence.booted[].platform.
- provider/cloud UNSUPPORTED_OPERATION error.data.platform for cloud
  Apple devices (reachable via deviceFieldsFromPublicPlatform).

Internal 'apple' emissions (selector-matching input, diagnostic
emitDiagnostic telemetry, session appLog state, replay .ad flags) are
left as-is. Adds focused tests pinning Apple perf memory support to the
leaf and a guard asserting no emitted platform field equals 'apple'.
