-`compile.sh` builds the `tuxreaperd` micro init before the main project. On supported hosts (`x86_64`/`amd64`/`aarch64`/`arm64`) it first tries the freestanding syscall implementation in `tuxreaperdasm.c`; on other architectures, or if the freestanding build fails, it falls back to the standard POSIX implementation in `tuxreaperdgnu.c`.

Pass `--force-libc-reaper` to skip the freestanding build and use the libc implementation directly.
 
 The web report is generated under `/tmp` and includes exact CTest output, test summaries, Docker integration output, a text rendition of the TUI flow, and the tuxreaperd zombie-reaping results. It requires `nc`, `netcat`, or Nmap's `ncat`; press `Ctrl-C` to stop the server. The default port is `8095`; pass a port after `--web-test-view` to override it. `--web-test-view --no-test` is invalid. Normal test runs include a Docker integration test using `debian:forky`, so Docker must be available. On systems with 1 GB or less of available memory, the script automatically uses a smaller build configuration and a single build job.
