asw-v01: modern CSS reset, fix README token docs, add watch.py live rebuild

- Rewrite 00-reset.css with :where()-wrapped zero-specificity rules
- Fix README token docs (--asw-* was incorrect, actual tokens use bare --*)
- Add watch.py (pyinotify-based auto-rebuild of dist/asw.css on src/ changes)

 ### CSS custom properties
 
-All visual tokens are exposed as `--asw-*` custom properties on `:root`:
+ASW defines a full set of semantic custom properties on `:root`. Key groups:
 
-```css
