chore: retrigger CI — Local Provision E2E stub failed on provisioning timeout (infra flake on main, unrelated to scheduler test addition)

Adds coverage for three previously-untested helpers in scheduler.go:
- TestClassifyTaskState_*: verifies OK states return empty, failure states
  are surfaced, and malformed JSON is handled gracefully.
- TestIsEmptyResponse_*: verifies empty bodies and sentinel strings are
  detected as empty, while actual content is not.
- TestA2AErrorFromBody_*: verifies JSON-RPC and plain error extraction,
  plus empty/invalid JSON fallbacks.

Full scheduler suite (49 tests) passes.
