fix(project): add pagination and org/ syntax to project list

- Follow API cursor pagination so --limit >100 actually works
- Add org/ prefix syntax to list projects for a specific org
- Add org/project syntax to show a single project directly
- Add --cursor/--prev flags for manual page navigation
- Add pagination_cursors table (schema v5) with composite PK
- Cache cursors per (command_key, context) for independent paging
- Clear pagination cursors on auth logout
- Regenerate SKILL.md for updated command help
