feat: register native APNs/FCM device token on push.native (P2 push, slice 3a — mobile)

[saucam]

What

Slice 3a — mobile half. Completes self-hosted native push: when the daemon advertises push.native (its native/relay transport sends via APNs/FCM directly — see codeoid #261), the client registers this device's native APNs/FCM token instead of an Expo token.

Change

• push-protocol.ts: PUSH_NATIVE_CAPABILITY = "push.native".
• push.ts registerForPush: picks the token type by what the daemon advertises —
  • push.native → getDevicePushTokenAsync() (raw APNs/FCM token; no EAS projectId needed),
  • push → getExpoPushTokenAsync() (unchanged, slice 2),
  • neither → register nothing (no push transport configured).

Backward-compatible: a daemon on Expo still advertises push; a daemon on native/relay advertises push.native. The registration wire message (push.register { token, platform }) is unchanged — platform already tells the daemon/relay whether to send via APNs or FCM.

Verification

tsc + eslint clean; expo export --platform web bundles 1020 modules. Device e2e (real APNs/FCM delivery + tap) needs an EAS dev build + a daemon running transport: native with your .p8 + Firebase service account — the one step that can't run headlessly.

Follow-ups

• Post-release: drop the local push-protocol.ts shim and import push.* + capabilities from @codeoid/protocol once a release ships them (both slices used the shim to decouple from the unreleased protocol).
• Standalone relay service (src/relay in codeoid) when the multi-user/hosted path is needed — mobile needs no further change (it already registers native tokens for relay too).

📋 PR Summary

What this PR does: Completes the mobile half of self-hosted native push by allowing clients to register raw APNs/FCM tokens when the daemon advertises the push.native capability.

Key changes:

• Added PUSH_NATIVE_CAPABILITY constant to the protocol shim.
• Implemented conditional token registration in registerForPush to select native tokens for push.native or Expo tokens for standard push.
• Maintained backward compatibility with existing Expo-based daemon configurations.

Areas affected: Push notification registration logic, Protocol definitions

Testing notes: Full end-to-end verification requires an EAS dev build and a daemon running with native transport configuration.

🔍 Code Review

This is a well-structured implementation that cleanly integrates native push support without disrupting existing Expo workflows. The capability-driven approach effectively abstracts the token selection logic, making the code easy to maintain and extend.

What's good:

• ✨ The capability-based routing logic is a strong pattern that ensures clear separation between protocol detection and implementation.
• ✨ Smart use of the protocol shim to decouple from the unreleased @codeoid/protocol package.
