chore(release): bump to v5.0 and update changelog

Major release marking the transition from memfd RAM-copy architecture
to direct file access, a full frontend performance overhaul, and
storage migration to /data/adb.

- Bump version to v5.0 (versionCode 500)
- Add comprehensive v5.0 changelog covering breaking changes,
  new features, performance improvements, and bug fixes
- CI workflow: add --no-daemon flag for Gradle in CI environments
- CI workflow: add R8 size verification step on release builds
  to catch regressions in APK shrinking effectiveness

+## v5.0
+
+### Breaking Changes
+- Storage relocated from `/data/misc/usbmassstorage/` to `/data/adb/Usbmanagement/` (auto-migrated on first boot)
+- memfd RAM copy architecture removed — images mount directly from disk with zero memory overhead
+
+### New Features
+- Device reboot button in the main toolbar with confirmation dialog
+- Path-based mount protocol for file:// URIs — daemon opens images directly via `/proc/pid/fd/N`
+- Images of any size now mount instantly regardless of available RAM
+- Import external disk images into managed storage from any file picker
+- Batch stat/blkid queries for image metadata (single shell call instead of 2N)
+
+### Performance
+- R8 full mode enabled — release APK shrunk ~70% via aggressive tree-shaking and class merging
+- Log.d/Log.v calls stripped from release builds via ProGuard rules
+- Baseline profile added for Compose runtime AOT compilation on first install
+- Compose stability configuration for deterministic recomposition skipping
+- All infinite animations migrated to `graphicsLayer` — draw-phase only, zero recomposition overhead
+- Shell.cmd() calls removed from main thread: composition body, onClick handlers, and store operations
+- File I/O in DeviceCard moved to background coroutine with LaunchedEffect
+- SharedPreferences reads wrapped in `remember` to prevent redundant disk access during recomposition
+- enrichWithSize and scanImages batch all shell calls into single scripts
+- Regex instances hoisted to top-level compiled vals across 5 files
+- Keyed LazyColumn items for stable item identity during list mutations
+- `@Stable` annotation on UiState for correct recomposition skipping
+- `configChanges` declared on MainActivity to prevent unnecessary Activity recreation
+
+### Bug Fixes
+- Fixed mixed mount protocol where sequential daemon calls cleared previously mounted devices
+- Fixed enrichWithSize running `java.io.File().length()` as unprivileged app context — now uses root shell
+- Fixed automount config corruption from unchained shell writes (newline vs `&&` join)
+- Fixed restartDaemon not killing parent service.sh loop alongside daemon process
+- DAC traversal fix: `/data/adb/` mode 700 blocked daemon — added `chmod o+x` in service.sh
+- Tightened `system_data_file` SELinux permissions — removed stale write/create from old storage path
+- Added `adb_data_file` rules to runtime SELinux patcher for storage migration
+- Added `untrusted_app fd use` and `shell_data_file read` to KSU rules
+
+### Module
+- Full storage migration with backward-compatible path detection on first boot
+- Old `/data/misc/usbmassstorage/` directory removed after successful migration
+- Gadget backup, automount config, and boot counter relocated to `/data/adb/Usbmanagement/`
+- Expanded SELinux policy for kernel→adb_data_file read access
+- Uninstall script updated for new data directory cleanup
+
 ## v4.0
 
 - One-shot create, format, and mount pipeline for streamlined disk setup
