feat(bmad-help): llms.txt support for general questions (#2230)

* feat(bmad-help): add _meta rows and llms.txt support for general questions

Register llms.txt URLs in module-help.csv via _meta rows so bmad-help
can fetch module documentation when users ask questions that don't map
to a specific skill.

* refactor(bmad-help): streamline llms.txt docs into existing skill sections

+  - **If the file exists:** Compare the content to what you wrote. If it has changed since you wrote it, acknowledge the external edits — show a brief summary of what changed — and proceed with the updated version. Then set status `ready-for-dev` in `{spec_file}`. Everything inside `<frozen-after-approval>` is now locked — only the human can change it. → Step 3.
 - **E**: Apply changes, then return to CHECKPOINT 1.
