fix(ai): include client version in ACP initialization

[murongg]

Summary

• require ACP client metadata to include a version
• send the Markra app version for document and inline ACP sessions
• add a regression test for the initialization payload

Why

Kimi Code 0.26.0 uses ACP SDK 0.23.0, which requires clientInfo.version. Markra omitted that field, so Kimi rejected the first initialize request with -32602 Invalid params.

Validation

• pnpm --filter @markra/app exec vitest run src/lib/acp-agent.test.ts — 18 passed
• pnpm --filter @markra/ai test — 245 passed
• pnpm --filter @markra/app typecheck:test — passed
• pnpm --filter @markra/app build — passed
• pnpm --filter @markra/ai build — passed
• pnpm --filter @markra/desktop build — passed, including vendor chunk verification

Known test issue

• pnpm --filter @markra/app test completed 1,836 of 1,837 tests successfully. The existing App.ai.test.tsx visible-editor test failed and was reproduced in the unmodified original worktree, so it is unrelated to this change.

Fixes #544
