[BUG]: Unhandled ENOENT error when submitting a message with a deleted file attachment #8807

Description

When a user attaches a file (e.g., @somefile.txt) to a message, but deletes that file from the file system before submitting the message, OpenCode crashes.

Bun.file(filepath).stat() throws an unhandled ENOENT error that prints raw to the TUI, breaking the display.

Steps to reproduce

1. Attach/mention a file in the input (e.g., @somefile.txt).
2. Delete the file from the file system.
3. Submit the message (Enter).

Alternatively (simpler):

1. attach/mention (e.g., @somefile.txt) any file and ask OpenCode to delete it (wait for completion)
2. up arrow, enter
