Without a zip extension or an unzip/7z binary Composer silently drops to
--prefer-source and mirror-clones every dependency, which exceeds its
300 s process timeout on phpunit.git. That took the Arch workspace job
from a 2m16s test-unit to a 16m08s failure. Debian never saw it because
apt pulls php-zip and unzip in as Composer dependencies; pacman does not.
Arch ships no zip extension and no php-zip package, so the extractor has
to be the unzip binary rather than the extension. Its mapping already
covers all five package managers.

ensure_php_toolchain installed the php and composer binaries and stopped
there. A distro ships the interpreter and its extensions as separate
packages, and ensure_command_present returns early once shutil.which
finds php - which it always does since the image bakes the interpreter -
so the extensions were never provisioned on any path.
composer then refused to resolve the vendor tree with
"phpunit/phpunit requires ext-dom * -> it is missing from your system"
and test-unit-php failed in every workspace job. The loaded ini list in
those logs shows 20-mbstring.ini present and no 20-dom.ini, 20-xml.ini
or 20-xmlwriter.ini, i.e. php-xml missing.
Extensions are now probed against php -m and installed from a per-manager
mapping, then re-probed so a package that does not deliver the extension
raises instead of leaving composer to fail later. The loop sits in
ensure_php_toolchain because both entry points pass through it: the image
build via utils.install.interpreters and the test run via
scripts/install/php.sh, so a prebuilt image is repaired at test time.

The committed line was 89 characters, one over the default limit, so
every autoformat run rewrote it and it kept reappearing as an unrelated
worktree change.
The unit suites had to install their toolchain on every run. The image
now carries the interpreters, so the make prerequisite finds them present.
The Composer vendor tree deliberately stays out of the image build: the
package cache is reached through the compose extra_hosts mapping, which
only exists for a running container, so a build-time composer install
would bypass the cache and talk to packagist directly. Fetching it from
the test target keeps it on the cached path.
test-unit-php and test-unit-ruby exited 0 whenever the interpreter or the
vendor tree was missing, so both suites were silently absent from every
gate. They now provision their toolchain through install-php/install-ruby
and fail loudly when that is impossible.
The three ensure_*_present helpers collapse into ensure_command_present
in system_pkg, and the ruby runner rejects an empty suite because
minitest reports success when nothing was required.
