Subject: [PATCH] Guard profile clearing against IPackageManager runtime drift

On some Android 17 builds, the manager compile flow crashes `VectorDaemon` with a
`NoSuchMethodError` in `ManagerService.clearApplicationProfileData()`. The daemon was
compiled against a hidden `IPackageManager` stub that declares
`clearApplicationProfileData(String)`, but some runtime `framework.jar` variants do not
expose that method at all.

We fix the issue by moving profile clearing behind a compatibility wrapper that reflectively
probes `IPackageManager` for `clearApplicationProfileData(String)`. When the method is
missing, we now log and skip profile clearing instead of crashing the daemon Binder thread.
