Add orch wait command for run status changes

[proboscis]

Summary

• add orch wait <RUN_REF> --until <status> [--timeout N]
• add a daemon-side WaitForStatus proto RPC that resolves the run once, polls daemon-owned run state, and returns when the target status is observed
• add CLI/daemon/orchapi tests plus regenerated Go/Python protobuf bindings

Flow

orch wait
  -> orchapi.WaitForStatus(...)
    -> daemon proto WaitForStatus
      -> resolve run ref in daemon
      -> poll store.GetRun(...) until target / timeout / impossible terminal state
      -> return matched run

Evidence

• go build ./...
  • passed
• architecture lint
  • uv tool run semgrep --error --config .semgrep/ ./internal/cli/ ./internal/monitor/ ./internal/daemon/ --exclude='*_test.go'
  • passed with 0 findings
• targeted tests
  • go test ./internal/cli -run 'Test(ParseWaitUntilStatus|RunWaitWithDeps|NewWaitCmdRequiresUntilFlag)'
  • go test ./internal/daemon -run 'TestHandleProtoWaitForStatus|TestGetAttachInfoResponseMapping|TestProtoClientDialTarget'
  • go test ./internal/orchapi
  • go test ./internal/query
  • all passed
• live command verification with an isolated temp repo/issues store and daemon
  • dynamic pr_open wait:

    {
      "issue_id": "orch-wait-demo",
      "ok": true,
      "run_id": "20260412-130000",
      "status": "pr_open"
    }

  • immediate waiting match:

    {
      "issue_id": "orch-wait-demo",
      "ok": true,
      "run_id": "20260412-130100",
      "status": "waiting"
    }

  • immediate done match:

    {
      "issue_id": "orch-wait-demo",
      "ok": true,
      "run_id": "20260412-130200",
      "status": "done"
    }

  • immediate failed match:

    {
      "issue_id": "orch-wait-demo",
      "ok": true,
      "run_id": "20260412-130300",
      "status": "failed"
    }

  • timeout path:
    • command: orch wait orch-wait-timeout#20260412-140000 --until done --timeout 1
    • stderr: daemon error: timeout waiting for orch-wait-timeout#20260412-140000 to reach status done (last status: running)
    • exit code: 10

Notes

• go test ./... still fails in this branch on an unrelated existing CLI test outside this change:
  • internal/cli/TestBuildAgentPromptCustomTemplate
  • failure: expected fallback prompt to include issue reference, got: "Issue: orch-3 - Custom"
