Greptile Summary

This PR prevents SD-card directory listings from throwing while handling non-tree SAF URIs.

• Moves URI parsing and child-URI construction inside the existing guarded error-handling path.
• Detects a non-tree URI before extracting its tree document ID.
• Returns a controlled Cordova callback error for unsupported directory URIs.

Confidence Score: 5/5

The PR appears safe to merge, with non-tree SAF directory inputs now failing through a controlled callback rather than escaping the listing path.

The normal initial and recursive listing flows continue to use tree URIs, while unsupported non-tree inputs return the same public error through a safer guarded path.

Important Files Changed

Filename	Overview
src/plugins/sdcard/src/android/SDcard.java	Adds an early SAF tree-URI validation and keeps URI-related failures within the directory-listing callback error path; no actionable regression was identified.
