fix: Update all skill/command paths to use ~/.claude/skills/

Problem:
- /skills command and all gateway skills used relative paths (cat skills/...)
- These only worked when run from cc-polymath directory
- When run from user projects (e.g., TypeScript monorepo), commands failed
  with "Skills catalog not found"

Root cause:
- Claude Code installs plugins to ~/.claude/plugins/marketplaces/
- Skills are made available globally in ~/.claude/skills/
- Commands were reading from current directory instead of global location

Solution:
- Updated all 100 files to use absolute paths: cat ~/.claude/skills/...
- Now /skills command works from ANY directory
- Gateway skills and INDEX.md files all reference correct paths

Files updated:
- 11 command files (commands/discover-*.md, commands/skills.md)
- 89 skill files (all SKILL.md, INDEX.md, and individual skills)
- 1092 total path replacements

Testing:
- Commands now work from any directory
- Plugin paths resolve correctly
- Global catalog at ~/.claude/skills/ is accessible
