Fix rish output capture broken by Shizuku 'Entering shell...' banner

[jairjacom]

Problem

On Android 17 (dev preview) with the thedjchi/Shizuku fork, the rish shell prints Entering shell... to stdout before executing commands.

This breaks every $(rish -c "...") output capture in Enhancify because the banner gets mixed into the result:

# Expected:
result=$(rish -c "pm install ...") # result = "Success"

# Actual on Android 17 / thedjchi Shizuku:
result=$(rish -c "pm install ...") # result = "Entering shell...\nSuccess"

String comparisons like [ "$result" == "Success" ] silently fail, causing installs to appear broken with no error message.

Fix

Added a rish_c() wrapper function that strips the banner line before returning output:

rish_c() { rish -c "$@" | grep -v "^Entering shell\.\.\."; }

All $(rish -c "...") output captures replaced with $(rish_c "...").

Backward compatible — grep -v is a no-op when the banner is absent (Android 14/15/16, standard Shizuku, other OEMs).

Files changed

• system/rish-install.sh
• system/rish-uninstall.sh
• modules/system/rish.sh
• modules/system/root.sh

Note: modules/constants.sh line 19 (rish -c 'exit' &> /dev/null) is intentionally left unchanged — output is discarded there, only exit code matters.

Tested on

• Device: Pixel 9 Pro XL (Android 17 dev, thedjchi/Shizuku fork)
• App: Piko-Instagram 439.0.0.37.89
• Result: Install + dex optimization completed successfully
