fix: clean up SkillEvaluator Tier 1 security findings in bundled skills

Findings from scanning skills/ + optional-skills/ with NVIDIA
SkillEvaluator's deterministic Tier 1 checks (PII/secrets, unicode
smuggling, script lint):

- pixel-art, pokemon-player: remove hardcoded /home/teknium/ personal
  paths (use ~ / portable phrasing); pokemon-player no longer claims
  machine-specific state as fact
- kanban-video-orchestrator: replace <path> angle-bracket token in
  frontmatter credits (flagged as XML-in-frontmatter prompt injection)
- comfyui, hermes-agent, unsloth, 1password, actual-setup: rephrase
  placeholder secrets so they no longer pattern-match real credentials
  (your-* placeholder convention, comment markers, {env:...} form)
- docker-management, pytorch-lightning: drop user:pass@ from example
  connection strings (env/secret-manager guidance instead)
- evm: break up Keccak round constant that Luhn-validates as a credit
  card number (digit-group underscores, value unchanged)

All targeted skills now pass pii+unicode+lint 3/3 except unsloth, which
retains scanner false positives only (Colab notebook IDs read as Bitcoin
addresses; an email inside a quoted upstream system prompt).
