Subject: Add ambient music and wild-mode tests

- generator_test.go:
  - TestThemeSoundPresetsAmbientPopulated: every theme has Ambient.Normal and
    Ambient.Wild with at least one drone or pulse frequency.
  - TestThemeSoundPresetsAmbientValuesBounded: gains/durations/intervals are
    positive and below conservative max values.
  - TestThemeSoundsJSON_neonAmbientRoundTrip: themeSoundsJSON unmarshals and
    contains ambient.normal and ambient.wild.

- integration_test.go:
  - TestKeyboardNavJS: verify p=ambient, f=flash hotkeys and nav hints.
  - TestIndexHTMLBakesSounds: verify index.html bakes window.SNONUX_SOUNDS.
  - TestThemeSelection: dynamically test all registered themes and assert
    generated sounds.json includes ambient data for each.
