chore: Exclude working files from repository

Removed internal working/reminder files from git tracking while keeping
them locally. These files are for development/planning use and not needed
by end users.

Files removed from tracking:
- BADGES_REMINDER.md
- POST_HACKERNEWS_REMINDER.md
- SEND_LANGCHAIN_EMAIL.md
- HN_ARTICLE_EMPATHY_MEMDOCS.md
- OUTREACH_EMAILS.md
- TODO_BADGES.md
- COMPREHENSIVE_COMPLETION_PLAN.md
- COMMERCIAL_READINESS.md

Updated .gitignore to exclude these files going forward.

Files remain available locally for development use but won't be
distributed in the PyPI package or cloned repositories.
