Wraps the three audio-thread `process` callbacks (`capture_process`, `playback_process`, `tap_process`) with `assert_no_alloc::assert_no_alloc(|| inner(...))`. The `headroom-cli` binary installs `AllocDisabler` as `#[global_allocator]` so any allocation inside one of those blocks during debug builds aborts the process with "memory allocation of N bytes failed". Each callback was renamed to `*_inner` to keep the thin wrapper function pointer stable for pipewire-rs's `process(fn_ptr)`. `assert_no_alloc`'s `disable_release` is on by default — release builds get the system allocator unwrapped and the macros become no-ops, so the audio thread pays zero runtime cost in production. Verified Positive smoke (5 s of 1 kHz sine through processed): daemon stays up across thousands of capture/playback/tap callbacks. No abort. Audio threads are alloc-free as designed. Negative smoke (temporarily inserted `Vec::with_capacity(1024)` inside `capture_process_inner`): daemon aborts (SIGABRT, exit 134) on the first audio callback with the expected "memory allocation of 1024 bytes failed" stderr message — confirming the harness is wired correctly and not silently a no-op. Sanity-check alloc reverted before commit. 185 tests pass; clippy clean at -D warnings --all-targets.
