fix(acp): replay history on session load

[huntharo]

Summary

This PR builds on MoonshotAI#2359 and includes both ACP fixes in one branch:

1. fix(acp): assign message ids to streamed content MoonshotAI/kimi-cli#2359: assign ACP messageId values to streamed content chunks after the ACP SDK bump to 0.10.0.
2. This follow-up: make ACP session/load replay restored history, including messageId fields on replayed user, assistant, and thought chunks, and expose restored session metadata.

I can rebase this PR after MoonshotAI#2359 lands so it contains only the session-load replay change. Alternatively, if maintainers prefer to take both fixes together, this PR can be merged as the combined ACP fix and MoonshotAI#2359 can be closed.

Changes

• Return a LoadSessionResponse with initial modes and models from session/load.
• Advertise transcript restore support as sessionCapabilities._meta.kimi.sessionHistoryReplay = true so clients do not have to infer replay behavior from loadSession alone.
• Replay persisted wire.jsonl records as ACP session/update notifications on load.
• Send messageId on restored user, assistant, and thought chunks using the message-id run tracking from fix(acp): assign message ids to streamed content MoonshotAI/kimi-cli#2359.
• Emit standard ACP SessionInfoUpdate title/updatedAt updates after prompt completion, and during session/load/session/resume.
• Return title/updatedAt metadata on session/load and session/resume under _meta.kimi.session.
• Record ACP/direct KimiCLI.run() turns to the session wire log so future loads have a replay source.
• Fall back to context text history for older sessions that do not have a wire log.
• Cover wire replay, context fallback, restored messageId, advertised replay capability, and session title metadata with tests.
