feat(theme): apply new color palette and polish UI

- Add theme variables and restyle popup/options using Primary 3 as background and Primary 2 as surfaces; accents use Primary 1.\n- Move Save to a footer section on the options page; add responsive layout and button variants.\n- Update icon build defaults to use Primary 2 for add-on and Primary 1 for toolbar icons.\n- Add build-and-commit helper to run build, stage generated assets, commit, and optionally push.\n- Add npm scripts: build:commit and build:commit:push.
