Fix: Vector + late-load bootloop on Samsung One UI 9 / Android 17 (android.ext.services stub)

[CreamPuffles]

Symptom:
​On Samsung One UI 9 (Android 17) with late-load root (KernelSU), activating Vector triggers a system_server crash-loop:
Required services extension package is missing, config_servicesExtensionPackage had defined with android.ext.services
​Cause:
​Samsung uses an RRO overlay to redirect config_servicesExtensionPackage to com.google.android.ext.services. Vector’s injected system_server reads the raw AOSP framework default (android.ext.services) instead of the overlay value. Since that package name is missing, PMS aborts. Additionally, Vector's daemon restarts system_server in a loop when it cannot attach immediately on late-load.
​Tested & Confirmed Working
​Device: Samsung Galaxy Z Fold 6 (SM-F956B)
​OS / Firmware: One UI 9 / Android 17
​Root Setup: KernelSU late-load
​Modules: Vector 2.2 + Zygisk Next (ZN) 1.5.2

​Resources
​Stub APK: https://drive.google.com/file/d/1M9yakSd-DuVWzq4CwXeC7kVlN_4z6Q4n/view?usp=drivesdk (Empty dummy package with package ID android.ext.services, no permissions, sha256: d57cd1e6fc25393de24cd8f0712c372afff2a21af8266e4925be28161356257c)

​Quick Fix Steps
​Install the stub APK:
pm install -r /sdcard/Download/android-ext-services-stub.apk

or via ADB: adb install -r android-ext-services-stub.apk

Patch /data/adb/modules/zygisk_vector/service.sh to stop daemon restart panics:
sed -i.bak 's|nohup .daemon.|nohup "$MODDIR/daemon" --system-server-max-retry=0 > /tmp/vec.log 2>&1 </dev/null &|' /data/adb/modules/zygisk_vector/service.sh

Activate late-load root & reload Zygote:
ksud post-fs-data
ksud services
setprop ctl.restart zygote

Verify hook status:
zygiskd64 status | grep -E 'zygote_states|modules64'

Expected: zygote_states:1, modules64:1,zygisk_vector

Result: System server remains alive, 0 PMS crashes, and Vector manager hooks attach properly. Cleanly uninstalls at any time with pm uninstall android.ext.services.
