feat(audio): attach the AI filter per-track after publication (way B, #0054)

Instead of webAudioMix on the room - which would also rewire playback (sink
selection through the AudioContext, LiveKit's Chrome echo workaround) - only the
local microphone track gets an AudioContext, via setAudioContext() right before
setProcessor(). The attach happens in onLocalTrackPublished, so a failing filter
can no longer prevent unmuting: the track is already published by then.

audioCaptureDefaults now never carry a processor key in any state; the
conditional spread only toggles noiseSuppression. A regression test covers the
active case too.

The gate stays closed. A single test client opts in via two localStorage keys
(ai-noise-suppression-dev plus the regular setting); the regular setting alone
stays inert. Four unit tests pin the attach order - setAudioContext before
setProcessor is exactly what v0.5.0 lacked - and the containment of a failing
attach. 77 tests green across the touched suites.
