ci(workflows): recompile agentic workflows with gh-aw v0.74.4 (#670)

The scheduled Clippy Fixer run failed during the safe_outputs job with:

    error: Repository lacks these prerequisite commits:
    error: 3c50dad
    Failed to apply bundle

Root cause: race condition between the agent and safe_outputs jobs. The
agent started from a main HEAD that advanced before safe_outputs ran,
and the safe_outputs job's `fetch-depth: 1` shallow checkout did not
contain the bundle's prerequisite commit. Upstream gh-aw issue #32467
documents this and ships a recovery path (git fetch --unshallow on
prerequisite-commit errors) in gh-aw-actions v0.74.3+.

Recompiling all 15 workflows with gh aw v0.74.4 pins
github/gh-aw-actions/setup@v0.74.4 (also bumps gh-aw-firewall,
gh-aw-mcpg, github-mcp-server, and the bundled Copilot CLI to current
versions).
