Verify Maestro MCP sync with current Docs API

[Copilot]

Validated the Maestro MCP against the updated openapi/maestro.json specification from Docs.

• API contract

  • Confirmed video and task endpoint paths match the spec.
  • Confirmed create-video parameters, model enums, duration bounds, and language limit are current.
  • Confirmed task retrieval request encoding remains aligned.

• Scope

  • No source or test changes were required; the existing Maestro implementation already reflects the upstream API updates.

• Fixes sync: update from Docs (6a841d9 docs: sync from PlatformBackend [automated]) #641
