* fix(#2801): add ingest-docs handler to gsd-tools init dispatch
The `/gsd-ingest-docs` workflow was broken because `workflows/ingest-docs.md`
called `gsd-sdk query init.ingest-docs` but the installed binary is `gsd-tools`,
and `gsd-tools init` had no `ingest-docs` case in its dispatch switch.
- Added `cmdInitIngestDocs` function to `init.cjs` and exported it; returns
`project_exists`, `planning_exists`, `has_git`, `project_path`, `commit_docs`
- Added `case 'ingest-docs'` to the `init` switch in `gsd-tools.cjs`
- Updated `workflows/ingest-docs.md` to call `gsd-tools init ingest-docs`
(line 55) and `gsd-tools commit` (line 292) instead of `gsd-sdk query ...`
- Regression test: `tests/bug-2801-ingest-docs-handler.test.cjs`
Closes#2801
