[1.1.0] Sonorities, an experimental sound-pattern panel

• 1.1.0 — New experimental Sonorities panel on the flip side of the Syllables tab's
  card: alliteration, consonant web, internal assonance, echo endings, with a live
  frequency-ratio badge per sound (see above). Random tab: words (built-in or personal) can now
  be tagged, liked, or excluded from the draw, with matching include/exclude filters. Ergonomics
  pass: checkboxes became pill-style toggles, secondary actions (Copy/Clear draft) became icon
  buttons, and the Syllables tab's action row moved above the textarea to match the French
  sibling plugin's layout. Fixed: several Sonorities palette colors had insufficient contrast
  with their white highlight text (as low as 2.54:1 against a 4.5:1 threshold) — darkened; and
  "Rhyme colors" was showing on both flip-card faces instead of just Structure.
