fix(inference): settle disposable probe cleanup

[senthilr-nv]

Outcome

Podman disposable readiness-probe cleanup now settles delayed exact-ID and deterministic-name removal state after one removal command. Cleanup returns only after both identities are absent within the fixed deadline, without retrying the mutation.

Reason

cleanupExactProbe() previously inspected the disposable probe immediately after podman rm. Rootless Podman can acknowledge removal before exact-ID and name-index reads publish the absence, which caused an indeterminate cleanup failure after otherwise valid provider work.

Changes

• Settle the pinned full probe ID before removal. Retry only timed-out read operations under the existing three-attempt inspect policy.
• Issue at most one full-ID removal command. Never remove by name or retry the removal mutation.
• Use a fresh 30-second read-only settlement window after removal. Require exact-ID and deterministic-name absence before success.
• Revalidate caller and engine authority around every read, mutation, final absence result, and rollback boundary.
• Reject malformed output, replacement identity, label or specification drift, foreign name ownership, invalid clocks, deadline overruns, and unproved rollback state.
• Add deterministic source tests for delayed absence, returned command errors with proved absence, hard-deadline boundaries, authority drift, foreign state, and rollback precedence.

Verification

• Focused provider source tests — 3 files and 110 tests passed.
• npm run checks:repository — passed.
• npm run typecheck:cli — passed.
• Staged pre-commit hooks — passed.
• Commit-message hook — passed.
• Pre-push CLI TypeScript hook — passed.
• git diff --check — passed.
• Independent review of binary diff 0a1e2ce8bd2f4ede25b7448359bed44a694c15b6b65e0102ee494a0c9666f8ea — approved.
• The diff contains no secrets, API keys, or credentials.

Review notes

This PR changes the shared Podman host-local-inference provider only. PR #10505 remains merged and unchanged. The cleanup correction uses exact runtime identity and existing provider authority; it does not change a durable receipt, inference route, or lifecycle contract.

Summary by CodeRabbit

• Bug Fixes

  • Improved cleanup of temporary local inference resources by verifying exact identity and confirmed removal.
  • Added bounded retries for delayed cleanup, timeouts, and transient inspection failures.
  • Prevented cleanup when resource details are ambiguous, stale, invalid, or no longer match the expected environment.
  • Added safeguards for invalid or non-advancing clocks.

• Tests

  • Expanded coverage for cleanup retries, deadlines, restoration failures, resource reuse, and environment changes.

📝 Walkthrough

Walkthrough

Podman host-local inference cleanup now uses configurable timing, exact identity validation, bounded removal settlement, authority checks, and injectable clocks. The test harness models lifecycle failures and validates retries, drift, deadlines, and invalid timing behavior.

Changes

Podman cleanup settlement

Layer / File(s)	Summary
Cleanup timing and inspection contracts src/lib/onboard/runtime-provider/podman-host-local-inference.ts	Adds cleanup timing options and separates lookup and inspection parsing from engine invocation.
Exact probe cleanup settlement src/lib/onboard/runtime-provider/podman-host-local-inference.ts	Validates probe identity and authority, retries transient observations, and verifies removal within a 30-second deadline.
Cleanup timing propagation src/lib/onboard/runtime-provider/podman-host-local-inference.ts, src/lib/onboard/runtime-provider/*test.ts	Passes configured timing through runtime, operation, receipt, recovery, resume, qualification, and inference probe paths.
Lifecycle harness and settlement validation test/helpers/podman-host-local-inference-test-harness.ts, src/lib/onboard/runtime-provider/podman-host-local-inference-cleanup-settlement.test.ts	Models Podman lifecycle outcomes, authority drift, reuse, and timing behavior. Tests validate cleanup settlement and failure handling.

- Around line 276-286: Update the rejection assertion in the test case “rejects
network-authority drift before probe removal” to expect the stable error-message
substring produced by the network-authority drift path, rather than using a
message-less toThrow(). Keep the existing assertions verifying probe retention,
container cleanup, and absence of forced removal unchanged.

In `@src/lib/onboard/runtime-provider/podman-host-local-inference.test.ts`:
- Line 49: Forward probeCleanupTiming from the harness to every harness-backed
probe-flow construction in the acceleration, Ollama, probe-inspection,
published-resume, and main lifecycle tests, matching the existing assignment in
the local-inference test. Ensure each construction uses
harness.probeCleanupTiming so cleanup does not fall back to
defaultProbeCleanupSleep.
