Android: Send button remains disabled when starting a session from a project linked to the home folder

Description

I can no longer start a new T3 Code session on Android when the selected project is linked to my home folder.

After entering a prompt, the send button remains disabled, so there is no way to submit the prompt or start the session.

Steps to reproduce

1. Open T3 Code on Android.
2. Select a project linked to the user’s home folder.
3. Choose to start a new session.
4. Enter text in the prompt field.
5. Observe the send button.

Actual behavior

The send button remains disabled after a prompt is entered. The session cannot be started.

Expected behavior

Entering a non-empty prompt should enable the send button and allow the new session to start.

Impact

This completely blocks starting new sessions from a home-folder-linked project on Android.

Environment

• Platform: Android
• T3 Code version: 1.0.3
• Android version/device: Android 17 / Google Pixel (model unspecified)
• Project location: User’s home folder
• Regression: This previously worked and is no longer working.

Start by reproducing the issue in the Android new-session flow with a project linked to the user's home folder, then inspect the prompt and send-button entry points. Verify the behavior with a non-empty prompt and confirm that the button enables and starts the session, while preserving the expected disabled state for an empty prompt.
