Three locations in execute-phase.md and quick.md used raw `git add
.planning/` commands that bypassed the commit_docs config check. When
users set commit_docs: false during project setup, these raw git
commands still staged and committed .planning/ files.
Add commit_docs guards (via gsd-tools.cjs config-get) around all raw
git add .planning/ invocations. The gsd-tools.cjs commit wrapper
already respects this flag — these were the only paths that bypassed it.
Fixes#1783
