Update codex to 0.118.0

[codex-acp-ci-app]

What's new

Previously failed tests and failure reasons:

• src/__tests__/CodexACPAgent/CodexAcpClient.test.ts:
  • should authenticate with key timed out (40s).
  • should authenticate with a gateway timed out (40s).
• src/__tests__/CodexACPAgent/mcp-session.test.ts:
  • should return configured mcp timed out (40s).
• Type-level test failures before fixes:
  • src/__tests__/CodexACPAgent/command-action-events.test.ts, src/__tests__/CodexACPAgent/terminal-output-events.test.ts, and src/__tests__/CodexACPAgent/load-session.test.ts failed because updated ThreadItem now requires commandExecution.source and agentMessage.memoryCitation.
  • src/__tests__/CodexACPAgent/fuzzy-file-search-events.test.ts failed because FuzzyFileSearchResult now requires match_type.
  • src/CodexAcpServer.ts and src/CodexEventHandler.ts failed typecheck due non-exhaustive switch handling after new protocol variants/events were added.

What I changed and why:

• Updated history/event switch handling for new protocol variants so unions are exhaustively handled and no event/item variant is silently dropped:
  • src/CodexAcpServer.ts
  • src/CodexEventHandler.ts
• Updated test fixtures to match regenerated app-server types introduced by the Codex update:
  • Added source: "agent" to commandExecution fixtures in command-action-events.test.ts and terminal-output-events.test.ts.
  • Added memoryCitation: null and source: "agent" in load-session.test.ts.
  • Added match_type: "file" in fuzzy-file-search-events.test.ts.

Previous code:

• do request -> attach listener -> wait for notification

Problem:

• if notification arrived in between, it was missed

The change is quite big, I rather expect minimal patch to fix typecheck and tests.
