/**
 * commit_docs bypass guard tests (#1783)
 *
 * When users set commit_docs: false during /gsd-new-project, .planning/
 * files should never be staged or committed. The gsd-tools.cjs commit
 * wrapper already checks this flag, but three locations in execute-phase.md
 * and quick.md used raw `git add .planning/` commands that bypassed it.
 *
 * These tests verify that every `git add .planning/` invocation (explicit
 * or via file_list) is preceded by a commit_docs config check.
