Commit message: fix: resolve types and tests after Codex update

Previously failing checks and reasons:

• src/__tests__/CodexACPAgent/CodexAcpClient.test.ts (should authenticate with key) failed because the data/auth-with-key.json snapshot no longer matched updated model/list output after the Codex upgrade (new gpt-5.4 entry, changed upgradeInfo, and updated migration markdown text/order).
• TypeScript failed in src/CodexEventHandler.ts with TS2366 because createUpdateEvent did not explicitly handle all ServerNotification variants introduced by the regenerated types.

What I changed and why:

• Updated src/CodexEventHandler.ts to explicitly handle new notification variants with intentional no-op cases:
  • command/exec/outputDelta
  • hook/started
  • hook/completed
    This restores exhaustive event handling for the updated schema and removes the type regression without adding a fallback.
• Updated src/__tests__/CodexACPAgent/data/auth-with-key.json to the current model/list behavior so the authentication-with-key snapshot reflects the post-upgrade payload.
