Subject: [PATCH] perf: shrink classes.dex from ~932KB to ~47KB
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Drop the unused UI library dependencies (material, appcompat, core-ktx,
tracing) and replace the Material app theme with a zero-cost framework
theme. None of these were referenced by the source — they were pulled in
solely by the Material theme. This app is headless (instrumentation +
broadcast receiver, no activity), so a framework theme is sufficient.

classes.dex: 953,956 -> 47,700 bytes
