Bumps github/gh-aw from 0.50.4 to 0.51.8.

Release notes

Sourced from github/gh-aw's releases.

v0.51.8

🌟 Release Highlights

This release delivers a notable breaking change with a smooth migration path, a quality-of-life CLI improvement, and enhanced traceability in generated workflow outputs.

⚠️ Breaking Changes

• app: frontmatter key renamed to github-app: — The GitHub App token configuration key has been renamed for clarity. A codemod is included to migrate your existing workflows automatically. Run gh aw update to apply the migration. (#19295)

✨ What's New

• --no-compile flag for update and upgrade — Skip the recompilation step when updating or upgrading workflows, giving you faster iteration when you want to defer compilation. (#19325)
• History links in generated footers — Issues, pull requests, and discussions created by agentic workflows now include a ◷ history link in their footer. Clicking it opens a pre-filtered GitHub search showing all items generated by that workflow, making it easy to audit workflow output at a glance. (#19321)

📚 Documentation

• Added a cache-memory filename safety warning to the workflow authoring guide — filenames with colons (e.g. ISO 8601 timestamps) break artifact uploads on Windows runners. (#19326)
• Added an explicit GitHub MCP requirement warning for all engine types in the workflow creation guide — clarifies that the Copilot coding agent cannot access api.github.com directly and must use the GitHub MCP server. (#19327)
• General documentation refresh covering features released on 2026-03-03. (#19330)

v0.51.7

🌟 Release Highlights

This release strengthens cross-repository workflow capabilities with flexible checkout fetch options and improved authentication, while delivering meaningful reliability fixes across safe-inputs, safe-outputs, and the gh aw status command.

✨ What's New

• Flexible checkout fetch refs — The checkout: config now accepts a fetch: option to retrieve additional Git refs after actions/checkout. Use fetch: ["*"] for all branches, fetch: ["refs/pulls/open/*"] for all open PR branches, or specify exact patterns. Agents are also given clearer context about available branches and fetch depth. This is especially useful for scheduled workflows that need to work on open pull-request branches.
