## Why
Existing login-keychain access rules identify the CLI as `codex`. Packaging it in an app bundle must preserve that code-signing identifier independently of the bundle identifier and provisioned App ID.
## What changed
- Sign the provisioned CLI with the identifier `codex`, retaining `com.openai.codex.cli` as its bundle identifier.
- Require the expected signing identifier and team during signature verification, and reject unexpected bundle identifiers, executable names, or package types.
- Document the identity distinction and keychain compatibility limits.
## Testing
Extend signing-driver tests to check the signing identifier, verification requirement, bundle metadata, and provisioned entitlements, and to reject altered bundle identity fields. These tests use generated credentials and stubbed native tools; they do not verify runtime keychain access or credential recovery.

## What changed
- Add a tag-release workflow gated by `CODEX_PROVISIONED_MACOS_CANDIDATE` for Apple Silicon and Intel macOS candidate artifacts.
- Package the CLI in `CodexCLI.app` with an embedded provisioning profile and a relocatable `bin/codex` launcher. Validate independently supplied profile, certificate, and team expectations before signing.
- Sign and notarize candidates, then verify signatures, entitlements, architecture, stapling, and Gatekeeper acceptance on macOS. Retain verified artifacts after package smoke tests pass.
- Filter code-mode smoke-test requests to `/v1/responses` so analytics requests are excluded from response parsing.
## Testing
Add tests for profile validation, launcher relocation and symlink handling, standard and provisioned signing flows, and rejection of signing, notarization, identity, and entitlement failures. The candidate workflow runs package smoke tests, including sandboxed code mode.
