- Ported functionality from `live_test.sh` to Rust, enabling end-to-end testing of `vmic` against a real PipeWire session. - Tests validate all major commands (`create`, `edit`, `route`, `list`, `delete`, `wipe`), topology transitions, and stream migrations. - Implemented robust cleanup mechanisms and guarded destructive operations to ensure safety. - Designed as an opt-in test, excluded from default `cargo test` runs.
