[dependabot]

Bumps github/gh-aw from 0.73.0 to 0.74.4.

Release notes

Sourced from github/gh-aw's releases.

v0.74.4

🌟 Release Highlights

This release delivers significant improvements to safe-outputs reliability, submodule checkout support, enhanced agent failure reporting, stronger security hardening against integer overflow, and a wave of community-requested fixes across MCP, protected-files, repo-memory, and lockdown checks.

✨ What's New

• Submodule-safe credential cleanup — New checkout.clean-git-credentials option prevents credential leaks when workflows use submodules, resolving a long-standing issue with persist-credentials: false in compiled lock files. (#32819)
• Automatic pull-requests: read permission inference — The compiler now infers pull-requests: read for activation jobs that include Vale pre-steps using gh pr diff, eliminating a common silent permission gap. (#32849)
• Larger repo-memory file cap — Default MaxFileSize raised from 10 KB to 100 KB, unblocking analysis of real-world source files. (#32826)
• Denied-command surfacing in failure reports — Agent failure reports now surface denied commands and include improved prompts for actionable debugging. (#32759)
• ctxbackground linter — New Go linter flags context.Background() calls when a ctx parameter already exists, enforcing consistent context propagation. (#32865)

🐛 Bug Fixes & Improvements

• Mentions policy respected in add_comment — Allowed mentions were being escaped due to a missing config pass-through; now correctly applied. (#32805)
• update_pull_request.update_branch permission failures non-fatal — Workflow-permission errors from branch-update calls are now treated as warnings rather than hard failures. (#32900)
• CLI not-found detection unified — Lowercase "not found" errors were previously missed; detection is now case-insensitive and centralized. (#32888)
• Cache-memory artifact upload path fixed — Threat-detection workflows were generating invalid artifact paths; upload now succeeds reliably. (#32733)
• Integer overflow guards — MergeUnique allocation sizing and the run-step sanitizer are both hardened against allocation-size overflow (addresses CodeQL finding #592). (#32842, #32841)
• create_pull_request chaos fallback — Prevents a spurious fallback when the branch already exists. (#32770)

📚 Documentation

• Multi-engine guidance in README — Explicit signal added to help users choose the right engine for their workflow. (#32889)
• LLM discoverability — llms.md and llms-full.txt added for LLM tool configuration and GEO discoverability. (#32744, #32867)
• Broken links fixed — Pattern links in patterns.md and engine link in engines.md repaired. (#32804, #32743)
