feat: add 10 new skill source types (17 total) with full pipeline integration

Add Jupyter Notebook, Local HTML, OpenAPI/Swagger, AsciiDoc, PowerPoint,
RSS/Atom, Man Pages, Confluence, Notion, and Slack/Discord Chat as new
skill source types. Each type is fully integrated across:

- Standalone CLI commands (skill-seekers <type>)
- Auto-detection via 'skill-seekers create' (file extension + content sniffing)
- Unified multi-source configs (scraped_data, dispatch, config validation)
- Unified skill builder (generic merge + source-attributed synthesis)
- MCP server (scrape_generic tool with per-type flag mapping)
- pyproject.toml (entry points, optional deps, [all] group)

Also fixes: EPUB unified pipeline gap, missing word/video config validators,
OpenAPI yaml import guard, MCP flag mismatch for all 10 types, stale
docstrings, and adds 77 integration tests + complex-merge workflow.
