Add CVE-2025-48543 exploit + auto RCS extraction for locked bootloader

CVE-2025-48543 (ART UAF → system UID):
- Works on Android 13-16 with patch < September 2025
- System UID (1000) can read any app's /data/data/ directory
- No bootloader unlock needed, no root needed
- Pushes exploit APK, executes post-exploit script at system level
- Tasks: extract_rcs, extract_app:<pkg>, disable_mdm, shell

extract_rcs_locked_device():
- Auto-selects best available exploit for the device
- Priority: CVE-2025-48543 → CVE-2024-0044 → content providers
- Extracts bugle_db + WAL + shared_prefs (key material)
- Falls back to SMS/MMS content providers if all exploits fail

"""CVE-2025-48543 — ART runtime UAF → system UID escalation.
Works on Android 13-16 with security patch < 2025-09-05.
Achieves system_server UID (UID 1000) which can read any app's
/data/data/ directory enough to extract bugle_db + encryption keys.
Locked bootloader compatible. No root needed.
The exploit uses a use-after-free in the ART runtime triggered by
a crafted app. We push and launch the exploit APK, which escalates
to system UID, then executes the requested task (e.g., copy bugle_db
to a world-readable location).
Args:
serial: ADB device serial
task: What to do once system UID is achieved:
'extract_rcs' copy bugle_db + keys to /sdcard/Download/
'extract_app:<pkg>' copy any app's data dir
'shell' drop a system-level shell payload
'disable_mdm' disable device admin / MDM
