[deep-report] Fix gh aw fix --write regression: empty features: block after mcp-cli removal

[github-actions]

Description

The gh aw fix --write codemod introduced a regression (filed as #30124): when features.mcp-cli is the only child of features:, removing it leaves an empty null features: key, causing the post-fix recompile to fail with:

error: got null, want object. Expected format: {}

This is actively worsening the aw-compat situation: the daily compatibility report (2026-05-04) shows 6/20 external repos still failing strict compile, with one repo worsening from 1 to 3 errors after running fix --write — caused by this bug.

Expected Impact

Blocks the compatibility recovery path for external repos. Fixing this regression allows the fix --write codemod to be safely re-run on all affected repos, moving the 6/20 failure rate toward 0.

Suggested Agent

Any coding agent with access to the gh aw fix codemod source. The fix is to remove the parent features: key when all its children are removed.

Estimated Effort

Fast (< 30 minutes) — single codemod logic fix with targeted test case.
