- test-fixtures/mock-claude: implement mock binary that writes 'stop' to FIFO then checks isatty(stdin), exiting 0 on TTY - tests/pty_integration.rs: test_pty_spawns_tty uses HookInstaller + PtySpawner to verify controlling TTY is established - src/lib.rs: expose hook module publicly - Cargo.lock: add libc dependency for mock-claude Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
