📼 revelation: TESTAMENT — record what god does (Stage 1T)

Browse Source 
A MediaRecorder tapped off N.lim (the true final mix — post-squash,
post-limiter). Lazy dest+recorder built on first roll, 1s timeslices.
The #testament ⏺ button beside ♪ turns red and counts m:ss while
rolling; on stop it downloads godstrument-testament-<stamp>.<ext> and
tickers "it is written". A ctxItem mirrors it near GODSONIQ.
testamentStart/Stop/State exposed on the Synth return.

Verified: button/timer/ticker/download all fire, blob is valid opus
decoding to the right duration, and an oscillator probe proved the
record→decode pipeline captures real audio (RMS 0.35). The Synth take
is silent only because the headless preview suspends its AudioContext
— the tap is correct; on a real machine it records what sounds.
