feat: sidebar CSS inspector — element picker, box model, rule cascade, quick edit

Extension changes for the visual CSS inspector:
- inspector.js: element picker with hover highlight, CSS selector generation,
  basic mode fallback (getComputedStyle + CSSOM), page alteration handlers
- inspector.css: picker overlay styles (blue highlight + tooltip)
- background.js: inspector message routing (picker <-> server <-> sidepanel)
- sidepanel: Inspector tab with box model viz (gstack palette), matched rules
  with specificity badges, computed styles, click-to-edit quick edit,
  Send to Agent/Code button, empty/loading/error states
