Live wire response + component display with OOB swaps on all examples

- All 6 examples show Component and Wire response as placeholders that
  fill with actual content when the demo is triggered (via OOB swaps)
- Wire response shows full wire content including component definitions
  (when not cached) and CSS style block
- Component display only includes defs the client doesn't already have,
  matching real sx_response() behaviour
- Add "Clear component cache" button to reset localStorage + in-memory
  component env so next interaction shows component download
- Rebuild tw.css with Tailwind v3.4.19 including sx content paths
- Optimize sx_response() CSS scanning to only scan sent comp_defs
