v1.2.0

Removed

• The input-gain attribute and inputGain property. They were documented and typed but never wired to a GainNode — setting them had no effect in any released version. Input gain is permanently a host responsibility: build a gain chain and pass the processed stream as inputStream (see docs/examples/host-gain.md). Consumer impact: TypeScript code referencing inputGain will no longer compile, and 'input-gain' is no longer listed in LatencyTest.observedAttributes — runtime behavior is otherwise unchanged. Policy note: this project treats removal of documented-but-never-functional API as a minor release; strict semver would classify any public API removal as major.
