* test(cli): keep IPC trace input under the Linux spawn limit

The listener-callsite CLI builds one trace argument from the full
application Evidence document. On 4 KiB-page Linux that string exceeds
MAX_ARG_STRLEN, so spawn throws E2BIG before the command starts. Keep the
document in a file, require the spawned argv to fit the single-argument
budget, and lock that budget through the test process registry.

* test(process): size the spawn ceiling from ARG_MAX and MAX_ARG_STRLEN

A payload at the single-string limit still fails execve with E2BIG when
the stack shrinks ARG_MAX below the rest of the image. Accept only the
bytes that fit both budgets, and skip that success spawn when the fixed
argv and environment already fill ARG_MAX.

* style(test): format files rejected by oxfmt in static checks

check:ci:fast failed format:check on the CLI fixture import and, after
merging main, on the admission test's new command-abort case.
