Temporary fork-only PR to validate the merged sequencer audit together with the Omnichord socket, Android and Gamma9001 release changes. This will be closed without merge after CI.

Add a fixed-size AF_UNIX/SOCK_SEQPACKET transport for local AMY wire messages, including peer credential checks, bounded queueing, cleanup safeguards, standalone regression tests, and focused CI.
Add a generic Android AAR service that renders AMY through Oboe/AAudio and accepts ordinary AMY wire packets over the private Unix transport. Include the minimal C-scale hello-world app plus Android build and emulator integration CI.
Document the generic Android AAR, Oboe backend, private SOCK_SEQPACKET client contract, readiness semantics, build requirements, and hello-world example.
Measure the raw AMY render stream and exact signed-16-bit buffer handed to Oboe during the Android hello-world integration test. Retain both WAVs and level statistics in CI, require byte-for-byte AMY-to-Oboe identity, healthy peak level, and no full-scale clipping.

Use AMY V10.0 for the audible hello-world. AMY's V control is a 0..10 bus/master scale and the final mixer applies a 0.1 factor, so the previous V2.0 setting was only 20% linear gain (about -14 dB relative to V10.0).

Validated at -2.721 dBFS peak with zero clipping and zero AMY-to-Oboe sample differences in Android AMY run 32630088165.
Make the Java hello-world a transport-only client. MainActivity no longer imports or starts AmyService and no longer loads a JNI/native client library. It uses Android LocalSocket SOCK_SEQPACKET directly and sends only ordinary AMY wire packets to filesDir/amy.sock.

Move service startup to an AAR-owned ContentProvider lifecycle hook, remove the hello-world C++/CMake client wrapper, and move test-only audio capture arming into CI so the example remains free of service/test control logic.
Add a fixed-size AF_UNIX/SOCK_SEQPACKET transport for local AMY wire messages, including peer credential checks, bounded queueing, cleanup safeguards, standalone regression tests, and focused CI.
