P10.1: candy-vibe higher-pitched SFX bank (sx / iOS assets)

Produce the first deliverable of the Candy-Crush vibe pass: a bank of bright,
glossy, higher-pitched SFX WAVs under assets/audio/, all in the exact canonical
iOS System-Sound format clear.wav uses (mono, 44100 Hz, signed-16-bit PCM).

Bank: swap, match, combo1..combo5 (ascending pentatonic run C6 D6 E6 G6 A6),
win (ascending arpeggio), lose (descending stinger). Every cue sits above
clear.wav's ~784 Hz fundamental; combo1<..<combo5 step strictly upward
(1047<1175<1319<1568<1760 Hz). Each loads via AudioServicesCreateSystemSoundID
with status 0.

Synthesized by the build-time tools/synth_audio.py (pure-Python additive
synthesis; the app never runs it) and converted with afconvert. Pitch verified
with tools/measure_pitch.py. Provenance (CC0) recorded in LICENSE.txt. No sx
code changes — engine wiring is P10.2/P10.3.
