docs(config): stop the workshop block documenting things that are not true

Three lies in one comment block, all the same family the tool sweep just
closed:

- `raw = true` was documented as a per-call bypass for output routing. It is
  not. The adaptive router takes it as `_raw_bypass` and ignores it; it is
  honoured only under the legacy CODEWHALE_CLASSIC_OUTPUT_ROUTING switch, and
  no tool advertises it. A user setting it got routing anyway, silently.
- The per-tool override example keys off `exec_shell`, `grep_files`, and
  `web_search`, all retired. An override written from this example matches
  nothing and does nothing, with no error.

Names the live tools instead and says plainly that the escape hatch is not
one. `raw` itself is left alone pending a decision on whether it should exist.
