+"""CLI comprehensive e2e tests.
+
+Extends test_cli_entry.py with edge cases exercised through the boxlite
+CLI binary (subprocess), covering behaviour that is CLI-specific:
+
+  - stderr capture
+  - large stdout through CLI pipe
+  - env var passing via --env
+  - working directory via --cwd
+  - multiple sequential execs on same box
+  - exec with non-existent command
+  - boxlite info / inspect
+  - concurrent boxes via CLI
