hypermistandClaude Opus 5.5 665f2f7f12 feat(opus): decode to float and with a priority in libSceOpusDec and libSceOpusCeltDec
Both modules route every decode export through one worker. Its checks
run in this order: state, packet, size, PCM pointer, capacity, then a
priority outside 20..100 (+0xA), then the state check (+1). Decode passes
priority 40.

The float exports decode 16-bit PCM into capacity / 4 * 2 bytes of the
caller's buffer and widen each sample in place, dividing positive
samples by 32767 and the rest by 32768. They return the float byte count.

The OpusDec *AndTimeout exports take a timeout for the AJM batch wait and
a pointer that receives the batch ID only when that wait fails. The host
decode is synchronous, so neither is used; the debt entry records this.

Read from libSceOpusDec.sprx and libSceOpusCeltDec.sprx, firmware 12.00,
not measured on a console.
