fix(onboard): preserve managed replacement diagnostics

[ericksoa]

Summary

Managed Docker replacement failures now report the exact transaction-owned container ID, exit state, and a bounded redacted log tail. This preserves the evidence needed to correct the messaging startup failure without weakening rollback or stable-running requirements.

Related Issue

Closes #9465

Changes

• Capture bounded Docker state and logs before each replacement-stability failure.
• Redact credential-bearing inspect and log values through the existing Docker diagnostic boundary.
• Prove that an exited replacement remains non-authoritative, is removed by exact ID, and leaves the rollback backup quiescent for owner cleanup.

Acceptance Criteria

• The final PR head passes openclaw-slack-pairing, hermes-slack, and token-rotation together in one trusted E2E run.
• The final PR head passes the full unfiltered trusted E2E matrix.
• All CI checks, both PR Review Advisor lanes, CodeRabbit feedback, and review threads are complete without unresolved findings on that same head.
• Every PR commit is GitHub Verified, and the admin merge is pinned to the audited final head.

📝 Walkthrough

Walkthrough

Managed Docker replacement failures now include runtime state and bounded redacted log tails. Cutover and bootstrap validation paths use the detailed error. Tests cover exited replacements, rollback cleanup, and activation diagnostics.

Changes

Managed replacement diagnostics

Layer / File(s)	Summary
Replacement instability diagnostics src/lib/onboard/managed-bootstrap/docker.ts	A shared error reports replacement runtime IDs, container state, and redacted log tails. Cutover, activation, bootstrap, and reconnect validation use this error when stability checks fail.
Diagnostic and rollback coverage src/lib/onboard/managed-bootstrap/docker.test.ts	Tests verify bounded diagnostics, exit metadata, runtime IDs, log redaction, rollback cleanup guidance, pre-cutover cleanup, and preservation of the stopped original container.

Estimated code review effort: 2 (Simple) | ~15 minutes

Merge Risk: 🔵 Low · up to 4a5b8

The change improves replacement-failure diagnostics, but the current tests do not verify that logs come from the exact replacement container, so diagnostics could be attributed to the wrong runtime without detection. The PR is otherwise mergeable with explicit owner follow-up on this bounded risk.

Sensitive-path security review — PASS

Reviewed commit under review: 4a5b875ff1db83c2ff32316aa099e57be45e5eae

Scope: managed Docker replacement failure diagnostics and their rollback tests.

• Authentication and authorization: no authentication, permission, or authorization behavior changes.
• Information disclosure: PASS. Diagnostics use the existing bounded collector (2-second calls, 120 log lines, 1,200-character redacted tail); tests cover NVIDIA provider-token and Slack-token redaction and the public length boundary.
• Trust boundaries: PASS. Evidence is collected only for the exact transaction-owned replacement ID after existing durable journal and identity assertions. Tests reject any other log target and prove identity drift creates no replacement or durable state.
• Injection and unsafe execution: no new command construction, shell execution, or untrusted executable input.
• Secrets and sensitive data: PASS. Raw inspect/log evidence does not bypass the existing Docker diagnostic redactor; secret canaries are asserted absent.
• Sandbox and container isolation: PASS. No isolation, mount, network, or container-creation behavior changes.
• Network exposure: no listener, egress, endpoint, or network-policy changes.
• Data integrity and availability: PASS. Replacement exits remain non-authoritative and fail closed without retry; rollback backup preservation, exact-ID cleanup, quiescent owner-cleanup guidance, and terminal removal of replacement/journal state after authorized cleanup are covered. Best-effort evidence collection remains bounded and cannot obstruct rollback.
• Supply chain and dependencies: no dependency, image, workflow, or artifact-source changes.

Findings: none.

This PR is now the explicit prerequisite requested in the human review on #9474: the shared managed-replacement diagnostics need to land here before #9474 removes its overlap and retains only the Discord-specific transport fix. @jyaunches, when you have a chance, could you review this prerequisite? Its current head is 4a5b875ff1db83c2ff32316aa099e57be45e5eae; automated CI, both advisor lanes, and the resolved CodeRabbit findings are green on that head.
