chore(skills): touchdesigner-mcp follow-ups

- Remove orphan skills/creative/touchdesigner/references/pitfalls.md
  left over from the rename commit (git add-then-edit instead of git mv
  meant the old file never got deleted).
- Honour $HERMES_HOME in setup.sh and SKILL.md setup invocation so
  profile-aware installs work correctly.
- Fix troubleshooting.md config path to use $HERMES_HOME instead of
  hardcoding ~/.hermes/.
- Add touchdesigner-mcp entries to skills-catalog.md and
  optional-skills-catalog.md for parity with blender-mcp/meme-generation.
