test(e2e): prove staging Brev exec readiness

[jyaunches]

Outcome

The general staging Launchable E2E now succeeds only after brev exec <owned-workspace-id> true proves remote execution readiness. Failed probes remain bounded and retain only the final bounded, redacted diagnostic, while the existing control-plane checkpoint and confirmed cleanup remain intact.

Reason

The control-plane checkpoint merged in PR #11270 proves workspace creation but does not prove that Brev can execute a remote command. This is the first deferred capability slice in epic #11250.

Changes

• Add a distinct remote execution readiness phase after workspace creation and before the retained control-plane checkpoint.
• Reuse BrevLaunchableFixture.waitForExec and its exact-owned-ID, bounded retry, redaction, and diagnostic contracts.
• Add fast evidence that readiness succeeds after two failed probes and uses only the owned workspace ID.
• Align workflow and artifact names with remote execution readiness and record the retry policy.
• Keep runtime identity, onboarding, inference credentials, OpenClaw execution, and issue [Linux][Agent&Skills] openclaw agent CLI enters infinite tool-call loop on simple text requests — TUI returns correct response #9880 classification deferred.

Verification

• npx vitest run --project e2e-support test/e2e/support/brev-launchable-fixture.test.ts — 29 tests passed.
• npm run test:changed — 45 integration tests and 29 E2E-support tests passed.
• npm run test:e2e-phases:check — 134 tests across 88 files passed semantic phase validation.
• npm run test:projects:check — 2,632 candidates have exact Vitest project membership.
• npm run e2e:assertions:check — assertion ratchet passed with 1,800 direct live assertions.
• npm run checks:repository — repository checks passed.
• actionlint .github/workflows/staging-launchable-full.yaml — passed.
• node --experimental-strip-types --no-warnings scripts/checks/e2e-mock-parity.mts --base origin/main --head HEAD — mock/live parity passed.
• Normal commit and push hooks passed after local build prerequisites were restored.
• The diff contains no secrets, API keys, or credentials.

Review notes

This changes a credentialed, billable remote-execution workflow. Brev credentials remain confined to the workflow-specific HOME, command probes persist no raw attempt artifacts, diagnostics are bounded and redacted before persistence or error reporting, operations remain bound to the persisted owned ID, and cleanup still requires two confirmed absence observations.

📝 Walkthrough

Walkthrough

The staging Launchable workflow and E2E tests now use remote-execution readiness terminology. The staging test waits for readiness, records it, and validates bounded retry behavior for Brev exec probes.

Changes

Staging remote-execution readiness

Layer / File(s)	Summary
Remote-execution readiness flow .github/workflows/staging-launchable-full.yaml, test/e2e/live/issue-9880-staging-launchable.test.ts, test/e2e/RETRY_INVENTORY.md	The staging test waits for remote-execution readiness after workspace creation, records remoteExecutionReady: true, and uses the remote-execution-ready completion classification. Workflow timeouts, labels, artifacts, and retry documentation use the same terminology.
Readiness retry validation test/e2e/support/brev-launchable-fixture.test.ts	The fixture test verifies two failed probes, success on the third probe, consistent use of owned-id, and no failure artifact after success.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 73080

This change adds a bounded remote-execution readiness check to the staging E2E flow before the existing control-plane checkpoint. No current merge-blocking risk is identified.
