docs: expand skill directory with all 18 official skills and descriptions for users who want to discover available skills

The skill directory previously listed only 4 of 18 official Anthropic skills
and had no descriptions. Users couldn't evaluate which skills to install
without clicking through to each GitHub repo.

Changes:
- Add all 18 official Anthropic skills organized by category (Documents,
  Design, Development, Productivity)
- Add descriptions for every skill (sourced from SKILL.md frontmatter)
- Fix broken handles: kasperjunge/commit → kasperjunge/commit-work,
  kasperjunge/pr removed (doesn't exist),
  dsjacobsen/golang-pro → dsjacobsen/agent-resources/golang-pro
- Fix kasperjunge/migrate-to-skills → kasperjunge/agent-resources/migrate-to-skills
- Add descriptions to all community skills
- Update llms-full.txt to match
