feat: Add support for IP address:port access

Update regex to support IP address format
Improve URL handling logic for IP addresses
Update error message to reflect supported formats
fix: Allow cleartext HTTP traffic

Add android:usesCleartextTraffic="true" to AndroidManifest.xml
Fix err_cleartext_not_permitted error
perf: Optimize regex performance

Precompile regex patterns as constants
Use precompiled URL_PATTERN and IP_PATTERN for matching
Reduce CPU overhead on each button click
