feat: legacy import — packs, examples, lab, themes, docs, lineage

Import from agentic-semantic-web/ into restructured repo:
- 7 packs (apache, caddy, flask, hugo, nginx, pandoc, python)
- shared error pages (403-503)
- 17 lab experiments (boilerplate, charts, misc)
- 31 example pages (charts, components, content, layout, vault)
- 2 themes (garden, trentuna stub)
- 4 docs (llms.txt, vocabulary, philosophy, agent-directive)
- lineage.md (Pico/Open Props/Charts.css history)
- Hugo mounts for lab/ and examples/

All agentic.css references updated to asw.css.
