feat: add 5 general-purpose / foundational skill sources

Adds the highest-starred general-purpose Claude Code / Codex skill
collections to scripts/sync_skills.py:

- obra/superpowers (194.6k stars, 14 skills) - methodology framework
- anthropics/skills (136.1k stars, 18 skills) - OFFICIAL Anthropic
- forrestchang/andrej-karpathy-skills (133.3k stars, 1 skill) - the
  famous Karpathy CLAUDE.md
- wshobson/agents (35.5k stars, 155 skills) - dev workflows across
  many plugin domains
- anthropics/claude-plugins-official (19.5k stars, 28 skills) -
  OFFICIAL Anthropic plugin skills (Discord, iMessage, Slack, etc.)

Install order reorganized into three tiers so higher-authority sources
win generic name collisions: bio/medical -> academic -> general/
foundational.

README source table grouped by scope. Skills count badge bumped to
1800+; sources badge bumped to 14. CHANGELOG updated under
[Unreleased].

+### Changed
+- Install order in `scripts/sync_skills.py` reorganized into three tiers: bio/medical → academic → general-purpose/foundational. Higher-authority sources (Superpowers, official Anthropic, Karpathy) are now last so they win generic name collisions.
