docs(agents): trim Do-Not-Touch to commitizen-specific traps

Drop `uv.lock` and the cache/build-artifact list (.mypy_cache, .ruff_cache, .venv, site, coverage.xml, ...) — those are generic lockfile/gitignore conventions that any modern agent already knows. Keep only the commitizen-specific files that get regenerated by cz bump, cz changelog, poe doc:screenshots, and poe test:regen, which an agent could not infer from convention alone.

 ## Do not touch
 
-These files are generated, tracked, or otherwise managed automatically. Do not edit them directly:
+These files are regenerated by Commitizen-specific tooling, so hand-edits get reverted on the next release or doc rebuild:
 
 - `CHANGELOG.md` — produced by `cz changelog`. Hand-edits will be overwritten on the next release.
 - `commitizen/__version__.py` — bumped by `cz bump` via the configured version provider.
 - `.pre-commit-config.yaml:rev:` lines under the `Commitizen` repo — bumped by `cz bump` (`version_files` in `pyproject.toml`).
 - `docs/images/cli_help/*.svg` and `docs/images/cli_interactive/*.gif` — regenerated by `uv run poe doc:screenshots`. See the [update-snapshots playbook](docs/contributing/agents/playbooks/update-snapshots.md).
 - `tests/**/*` snapshot files used by `pytest-regressions` — regenerated via `uv run poe test:regen`.
-- `uv.lock` — only modify by changing dependencies in `pyproject.toml` and running `uv sync`, never by hand-editing.
-- Anything under `__pycache__/`, `.mypy_cache/`, `.ruff_cache/`, `.venv/`, `site/`, `coverage.xml`, `junit.xml`.
