Device File Search

Use shell (device-side), not workspace exec.

• Quick latest list: shell("sh -lc 'ls -1t /storage/emulated/0/DCIM/Camera | head -n 20'")

• Wider image search: shell("sh -lc 'find /storage/emulated/0 -type f \\( -iname \"*.jpg\" -o -iname \"*.jpeg\" -o -iname \"*.png\" -o -iname \"*.webp\" \\) | head -n 400'")

• Wider video search: shell("sh -lc 'find /storage/emulated/0 -type f \\( -iname \"*.mp4\" -o -iname \"*.mov\" -o -iname \"*.mkv\" \\) | head -n 400'")

• Verify one candidate path: shell("ls -l /storage/emulated/0/DCIM/Camera/<filename>")

Reliability Rules

• Prefer /storage/emulated/0/... over /sdcard/... (symlink issues can hide find results).
• If /sdcard must be used, use find -L /sdcard ....
• After editing/saving, prioritize files modified in the last few minutes.
• Before telling the user "not found", verify at least 2 directories + 1 wide search.

After Found

• Keep the exact absolute path in memory for the rest of the task.
• Reuse the same path for upload/share actions.
• If upload fails, retry with the same verified path before starting a new search.
