Responses provider tools ship; Agent.updateInstructions() added

Minor Changes

• Add OpenAI Responses provider tools for web search, file search, and code interpreter. - #1674 (@toubatbrian)

Patch Changes

• Add Agent.updateInstructions() to update an agent's instructions mid-session (parity with Python). The change propagates the new instructions through the active AgentActivity, records an AgentConfigUpdate in the chat and session history, and syncs the realtime/stateless contexts. For OpenAI realtime, per-response instructions now preserve the session-level instructions instead of replacing them. - #1674 (@toubatbrian)

• Default OpenAI reasoning effort to none for gpt-5.4-mini. *-chat-latest models no longer send a default reasoning_effort (Python parity, and the API only accepts medium for them). - #1674 (@toubatbrian)

• Updated dependencies [51281bf, 51281bf, 51281bf, 51281bf, 51281bf, 51281bf, 51281bf, 51281bf, 51281bf, 51281bf, 51281bf, 51281bf, 49f7567, 51281bf, 51281bf, 51281bf, 51281bf, 51281bf, 51281bf, bfad336, 51281bf, 51281bf, 51281bf]:
