Describe the bug

Describe the bug

The goose projects command panics with a character boundary error when processing Japanese text. Specifically, it fails when trying to slice a UTF-8 encoded Japanese string at byte index 37, which falls in the middle of the Japanese character '内' (bytes 36-39).

To Reproduce
Steps to reproduce the behavior:

Set up an environment with Japanese text in project descriptions or session names
Run goose projects command in terminal
The following panic error occurs:
thread 'main' panicked at crates/goose-cli/src/commands/project.rs:203:52:
byte index 37 is not a char boundary; it is inside '内' (bytes 36..39) of `現在のディレクトリの変更内容からGitHub PRを作成してください。 ...

Expected behavior

The command should display the project selection screen normally, even when project information contains Japanese text.
