fix(security): disable semgrep/semgrep container — Critical/High CVEs, no upstream fix available

[Copilot]

semgrep/semgrep:latest (sha256:bdf7013...) carries 8 Critical and 32 High CVEs (curl, python3, sqlite-libs, git system packages; mcp@1.23.3, wheel@0.45.1 Python packages; Go stdlib go1.25.10). Confirmed semgrep/semgrep:1.172.0 (newest available) ships identical vulnerable package versions — no patched image exists upstream.

Changes

• shared/mcp/semgrep.md — Remove mcp-servers container block; replace with security comment (mirrors the brave.md pattern used for mcp/brave-search in [container-image-scan] Container findings for docker.io/mcp/brave-search #48546)
• daily-semgrep-scan.md — Drop schedule: daily trigger; keep workflow_dispatch for manual re-activation; add comment referencing this issue
• actions-lock.json — Remove semgrep/semgrep:latest pinned digest entry

Re-enabling

When semgrep ships a patched image:

1. Restore the mcp-servers block in shared/mcp/semgrep.md
2. Update the digest in actions-lock.json
3. Restore schedule: daily in daily-semgrep-scan.md
4. Run make recompile

• Fixes [container-image-scan] Container findings for semgrep/semgrep:latest #49520

Hey @Copilot 👋 — thanks for addressing this critical security issue! The semgrep vulnerability remediation looks solid. Here are a few things to finalize:

• Mark ready for review — This PR is currently a draft. Once you have confirmed the re-enablement plan with maintainers, mark it as ready.
• Verify rebuild — Per the body, make recompile needs to be run after changes to compiled lock files. Confirm this step is completed.
• Cross-check lock files — The changes span both actions-lock.json and the pkg/ pin files; ensure all references to semgrep/semgrep:latest are consistently removed.

The changes follow the precedent set in #48546 for the brave-search container (security comment + removal from locks). This looks like a solid security-first decision given the upstream situation. Ready to proceed once draft status is cleared! 🎯
