feat: shared Help base, Google OAuth live, new personas, cleanup

- cortex/static/HELP.md: shared Help & Reference base served to all users
- help.html: loads shared base + appends persona-specific HELP.md if present
- inara/HELP.md: cleared (content moved to shared base)
- Google OAuth: registered scott.idem@oneskyit.com; flow now working end-to-end
- .gitignore: exclude home/**/sessions/ (runtime logs)
- New personas tracked: home/holly/persona/donut/, home/scott/persona/developer/
- Removed orphans: holly/, personas/, cortex-holly.service
- CLAUDE.md: updated current state and recently completed list to 2026-03-27
