/**

* PTY/Interactive Session Tests
|
||||
*
|
||||
* These tests verify that:
|
||||
* 1. Claude CLI is spawned with correct flags (--dangerously-skip-permissions)
|
||||
* 2. Interactive sessions open a TTY
|
||||
* 3. Input can be sent to the terminal
|
||||
* 4. Output is received from the terminal
|
||||
* 5. The session properly detects idle/working states
