• scripts/README.md: Added prominent disclaimer for conceptual HTTP client example

CI/CD Configuration Fixes

• .github/dependency-review-config.yml: Fixed format for allow-dependencies-licenses and deny-packages (changed from objects with package-name keys to simple string arrays)

• .github/workflows/security-audit.yml: Added error handling and continue-on-error for PR comment posting to prevent failures when called from workflow_call without proper permissions

Testing

• My code follows the project's style guidelines
• I have performed a self-review of my own code
• I have commented my code, particularly in hard-to-understand areas
• I have made corresponding changes to the documentation
• My changes generate no new warnings
• I have added tests that prove my fix is effective or that my feature works
• New and existing unit tests pass locally with my changes

Test Details

• Build Verification: cargo build - 0 errors, all 6 crates compile successfully
• Test Suite: cargo test --workspace --lib --bins - 56 tests passing (10 core, 7 gui, 4 plugins, 26 protocol, 5 scripting, 4 tui)
• Code Quality: cargo clippy -- -D warnings - 0 warnings
• Dependency Resolution: All package updates applied via cargo update with no conflicts
• CI Configuration: Fixed dependency review config format and security audit permissions

Screenshots (if applicable)

N/A - Infrastructure, documentation, and CI/CD configuration changes only.

Performance Impact

• This change has no performance impact
• This change improves performance
• This change may reduce performance (explain why it's worth it)

Minor performance improvements expected from dependency updates (regex optimization, tokio async runtime improvements).

Security Considerations

• This change has no security implications
• This change improves security
• This change requires security review (explain)

Security improvements include rustls TLS updates, input validation enhancements in newer dependency versions, documented sandboxing model for Lua scripting (removes os.execute, io.*, require), and fixed CI/CD security audit workflow configuration.

Impact Summary

Files Modified: 15 (+1,340/-270 lines net)

• 4 GitHub workflow files (updated Actions versions)
• 2 GitHub configuration files (fixed CI/CD issues)
• 5 documentation files (CHANGELOG, README, CONTRIBUTING, 2 new in scripts/)
