feat(chatmodes): Add HLBPA (documentation architect) chat mode (#278)

* feat(chatmodes): Add HLBPA (documentation architect) chat modes

- HLBPA is a high-level, big-picture architect for systems documentation
- It can be used either in VSC as usual or dropped in coding agent for auto-updates
- Depends on user's prompting skills to get the best results
- Will default to a more generalist mode if not enough context is given
- Minor updates to README and CONTRIBUTING to fix formatting errors

* chore(chatmodes): Remove copy from md fence in HLBPA chat mode

- Copilot complains about the copy in the md fence
- Isn't likely to be used in this context anyway
