ci: enforce workflow policy

[albert20260301]

Summary

• pin every third-party GitHub Action in the semantic-title, release, test, and integration workflows to its reviewed commit SHA
• move Linux jobs to ubuntu-24.04
• retain the repository's .node-version and .bun-version runtime contracts

Impact

This is workflow-only hardening. It does not change the SDK packages, release contract, or runtime behavior. The existing community-file PR #180 modifies a separate legacy semantic-workflow path; it remains unsafe to merge because it would add a duplicate noncompliant check.

Verification

• bash /root/.openclaw/workspace/scripts/validate-workflow-policy.sh /root/.openclaw/workspace/code/altertable-js
• git diff --check
• YAML parse for all modified workflows
• bun run lint
• bun run test

@francoischalifour could you review this?

I picked you because recent workflow-path history points to your ownership of the release and semantic-title automation. CI is pending. The main review focus is preserving the Node/Bun trusted-publishing setup while pinning the actions and runner images.

@francoischalifour could you take a look when you have capacity?

This workflow-policy change is green and has been awaiting review since the August 10 request. The review focus is preserving the Node/Bun trusted-publishing setup while keeping the action pins and Ubuntu 24.04 runner updates correctly scoped.

@francoischalifour follow-up: this is still green and unreviewed after three days. Could you review that the trusted-publishing workflow remains intact and the runner/action-pin changes stay correctly scoped?
