Subject: [PATCH] fix(fdroid): cap Gradle heap + drop daemons so the build
 survives host RAM pressure

The reproducible build OOM-killed the Gradle daemon ('daemon disappeared
unexpectedly') mid flutter-build-apk on the shared runner. The app's
gradle.properties reserves -Xmx8G+4G metaspace (~12G), and the fdroid
build also compiles tesseract4android from source first (its daemon
lingers), so combined peak RAM trips the OS OOM-killer under contention
(the same build succeeded on a quieter host earlier). Scope the fix to
the fdroid build (don't touch the committed 8G the play/local builds
rely on): run tesseract's gradle with --no-daemon so it frees memory
before the app build, and append a lower -Xmx4g + org.gradle.daemon=false
override to gradle.properties in prebuild (last-key-wins; F-Droid runs
the same steps and memory settings don't change output bytes, so it stays
reproducible).
