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.

+# ASW Python Dev Server Pack
+
+Drop-in replacement for `python -m http.server` with ASW-styled error pages and directory listings.
+
+## Usage
+
+```bash
+# Copy to your project
+cp asw_server.py /path/to/project/
+
+# Run it
+python asw_server.py              # port 8000
+python asw_server.py 3000         # custom port
+python asw_server.py 3000 /dir    # custom port + custom directory
+```
+
+## What you get
+
+- **ASW-styled error pages** for all HTTP error codes (403, 404, 500, etc.)
+- **ASW-styled directory listings** replacing the browser-default autoindex
+- **Auto port fallback** — if 8000 is busy, tries 8001, 8002… up to 10 attempts
+- **Inline styles** — no external CSS dependency, works even when serving offline
+
+## How it works
+
+`ASWHandler` subclasses `SimpleHTTPRequestHandler` and overrides:
+- `send_error()` — returns ASW-styled HTML instead of the default ugly page
+- `list_directory()` — returns a clean table layout instead of raw `<pre>`
+
+Styles are inlined directly in the response — no link to `asw.css` required.
+The colour scheme matches the full ASW dark theme.
+
+## No dependencies
+
+Just Python 3 standard library. Nothing to install.
