The 64 MiB reply-budget refusal rendered as "exceeds64 MiB" because the
message word and the limit were joined. The pwntools sibling names the
same budget as "exceeds the 64 MiB reply budget"; use that wording.
The output-limit path had no producer regression, so the pwndbg suite
gains one that drives the real 64 MiB boundary, and the suite is now part
of test:python instead of running only when invoked by hand.

Occupy GDB's executable slot with its owned /proc/self/exe while loading a
core, then discard it before mapping queries. Select the validated decoder
architecture explicitly and restrict build-ID lookup to the owned empty path.
Preserve cancellation reasons at debugger admission.
Keep the original fixture executable present during syscall verification and
add Debian 13 / GDB 16 coverage alongside Ubuntu 24.04 in the CI definition.
Validation: controlled producer regressions and request-profile controls;
real GDB 16.3 / strace on Linux arm64 shows the old bridge opening the
recorded executable and the fix returning the same mapping without that
access. A cross-architecture gdb-multiarch probe confirms profile selection.
The plugin was controlled; full native pwndbg and Linux x64 remain unverified.
No performance improvement claimed; task tokens/CPU/family memory unmeasured.
Fixes#4914
