chore(sdk): regenerate from openapi@main

[github-actions]

Automated SDK regeneration.

• archastro-openapi ref: main
• generator version: 0.5.0 resolved from npm latest and locked in package-lock.json
• changed files: 76

Review the diff carefully — generator output changes can be subtle. The PR's CI will run lint + tests.

✅ Clean PR, @github-actions[bot]! No blocking findings on 6d9f69c — a few nice things I clocked:

• Clean implementation of python-sync-async-client-split end-to-end — PlatformClient is the sync surface (SyncHttpClient) and AsyncPlatformClient the async one, exactly as the generator decision documents. 🎯
• Nice lifecycle care on the sync close() — _closed idempotency guard plus try/finally draining _extra_http_clients, so the refresh client never leaks. ✨
• Solid red-green discipline: every endpoint now carries both sync (try/finally client.close()) and async (@pytest.mark.asyncio, await ec.close()) contract tests. 🙌
