[Bug]: LLDB doesn’t list or resolve breakpoints for System.load-loaded .so under app private dir on Android (namespace + rendezvous?)

### Description

**Environment**
• Emulator/Android: Android 13 / 14, arm64
• App: android:debuggable="true", extractNativeLibs=false (also tried true for control)
• How .so is loaded:
• System.load("/data/data//files/.../libX.so")
• Also repro with System.loadLibrary() via a custom ClassLoader pointing to the same private dir (both call android_dlopen_ext)
• Toolchain: Android Studio , NDK , lldb-server from NDK, host LLDB
• Launch mode: Debug (lldb-server user = app UID u0_aNNN) / Attach (also repro)

**Repro steps**
1. Put an unstripped libX.so into /data/data//files/... and load it at runtime with System.load(absPath).
2. In LLDB:

```
settings set target.process.stop-on-sharedlibrary-events true
break set -n android_dlopen_ext
break set -n dlopen
log enable lldb dyld
```

3. After the load occurs, run:
```
image list -b
```
Observed: the module is not listed; breakpoints in that library remain pending.

4. /proc//maps shows the library mapped, and the code in the library executes correctly.
5. lldb-server is confirmed to run as the app UID (e.g., u0_aNNN), so it should have permission to read the private dir.

**Expected**
After the rendezvous eAdd/eAddModules events, LLDB should register the newly loaded module so that it appears in image list and breakpoints resolve automatically.

**Actual**
• log enable lldb dyld shows rendezvous activity around the load (eAdd / eAddModules), but the module is not added to the target’s module list.
• image list does not contain the .so from the app private directory, so breakpoints remain pending and symbols don’t resolve.

**Notes**
• Reproduces with both System.load and System.loadLibrary (custom ClassLoader) which call android_dlopen_ext.
• Reproduces regardless of extractNativeLibs setting (true/false).
• lldb-server is running under the app UID, so this does not look like a simple permission issue.
• This may be related to handling of Android linker namespaces / rendezvous on private-dir loads.
