feat(security): add GHSA detector-review pipeline and OpenGrep CI workflows (#69483)

* feat(security): add GHSA detector-review pipeline and OpenGrep CI workflows [AI-assisted]

Stand up an end-to-end pipeline that turns every published openclaw GitHub
Security Advisory into a reusable OpenGrep rule, and wire the compiled rules
into manual-dispatch GitHub Actions workflows that publish SARIF to GitHub
Code Scanning.

The pipeline is harness-agnostic: any coding-agent CLI (Rovo Dev, Claude
Code, Codex, OpenCode, or anything you can shell out to) can drive it via
the runner script's --harness flag. Built-in adapters cover the four common
harnesses; --harness-cmd '<template>' supports anything else with shell-style
{prompt}/{model}/{output_file} substitution.

Pipeline pieces:

- scripts/run-ghsa-detector-review-batch.mjs runs your chosen coding harness
  in parallel against every advisory using the agent-agnostic detector-review
  spec at security/detector-review/detector-review-spec.md. Each case
  produces an opengrep general-rule.yml (precise) and broad-rule.yml
  (review-aid), plus a coverage-validated report against the vulnerable
  commit's changed files.
- scripts/compile-opengrep-rules.mjs walks a run directory, rewrites each
  rule's id to ghsa-detector.<ghsa>.<orig-id>, injects ghsa/advisory-url/
  detector-bucket/source-rule-id metadata, and uses opengrep itself to drop
  rules with InvalidRuleSchemaError so the published super-configs load
  cleanly.

Compiled outputs:

- security/opengrep/precise.yml     (336 rules)
- security/opengrep/broad.yml       (459 rules)
- security/opengrep/compile-manifest.json    (per-rule provenance map)

CI workflows (manual workflow_dispatch only):

- .github/workflows/opengrep-precise.yml
- .github/workflows/opengrep-broad.yml

Both install a pinned opengrep, run opengrep scan against src/, upload SARIF
to Code Scanning under categories opengrep-precise / opengrep-broad, and use
continue-on-error: true so findings never block the workflow.

Detector-review spec and assets:

- security/detector-review/detector-review-spec.md   the agent-agnostic spec
  the runner injects into each per-case prompt
- security/detector-review/references/{detector-rubric,report-template}.md
- security/detector-review/scripts/init_case.py
- security/prompt-suffix-coverage-first.md   mandatory prompt addendum that
  enforces coverage-first validation (rule must catch the OG vuln, not just
  pass synthetic fixtures)

Docs:

- security/README.md          end-to-end flow, supported harnesses, regen recipe
- security/opengrep/README.md compiled-config details + recompile recipe

* security: tighten GHSA OpenGrep detector workflow

* chore: refine precise opengrep workflow

* chore: remove stale opengrep metadata

* fix: harden GHSA OpenGrep workflow

* ci: split OpenGrep diff and full scans

* chore: remove performance-only opengrep rule

* ci: use OpenGrep installer path

* chore: enforce opengrep rule metadata provenance

* chore: generalize opengrep rule compilation

* docs: align opengrep rulepack guidance

* chore: support generic opengrep rule sources

* fix: validate opengrep rulepack-only changes
