feat(skills): add autonomous-loops and plankton-code-quality skills

- autonomous-loops: 6 loop patterns from simple claude -p pipelines to
  RFC-driven DAG orchestration (Ralphinho, infinite-agentic-loop,
  continuous-claude, de-sloppify pattern)
- plankton-code-quality: write-time enforcement integration guide
- README: updated directory listing and Plankton description

-[Plankton](https://github.com/alexfazio/plankton) is a recommended companion for code quality enforcement. It provides automated code review, linting orchestration, and quality gates that pair well with the ECC skill and hook system. Use it alongside AgentShield for security + quality coverage.
+[Plankton](https://github.com/alexfazio/plankton) is a recommended companion for write-time code quality enforcement. It runs formatters and 20+ linters on every file edit via PostToolUse hooks, then spawns Claude subprocesses (routed to Haiku/Sonnet/Opus by violation complexity) to fix issues the main agent missed. Three-phase architecture: auto-format silently (40-50% of issues), collect remaining violations as structured JSON, delegate fixes to a subprocess. Includes config protection hooks that prevent agents from modifying linter configs to pass instead of fixing code. Supports Python, TypeScript, Shell, YAML, JSON, TOML, Markdown, and Dockerfile. Use alongside AgentShield for security + quality coverage. See `skills/plankton-code-quality/` for full integration guide.
