kevinveenbirkenbachandClaude Opus 5.5 2756fd56f1 fix(cache): install CA anchors where every update-ca-trust family reads them
The Fedora and CentOS Stream workspace jobs failed TLS to pypi.org,
registry.npmjs.org and repo.packagist.org (CERTIFICATE_VERIFY_FAILED,
curl error 7). package-frontend/ca.sh put the frontend CA into the Arch
anchor dir /etc/ca-certificates/trust-source/anchors, which p11-kit on
the RedHat family never reads.

Probing for the anchor dir does not fix it: with-ca-trust.sh creates
both /etc/pki/ca-trust/source/anchors and
/etc/ca-certificates/trust-source/anchors on every update-ca-trust host,
so the probe in registry-ca.sh already picks the RedHat dir on a reused
Arch runner. Both scripts now install into both dirs, rebuild only when
one of them changed, and take CA_ROOT so unit tests run them against a
fake root.

# Install the registry-cache MITM CA certificate into the runner
# container's system trust store before dockerd starts.
#
# The `registry-cache` service in compose.yml runs
# rpardini/docker-registry-proxy and performs SSL bumping on every
# outbound docker registry pull. Inner dockerd MUST trust the proxy's
# self-signed CA, otherwise every HTTPS pull fails with x509 errors.
#
# Idempotent: safe to run on every dockerd restart. The bind-mount-absent
# case is reserved for solo-service debugging (no `ci` profile, registry-
# cache not present); in normal operation compose.yml gates `infinito` on
# `registry-cache` being healthy, so the CA is always on disk by the time
# this script runs. A mounted dir with no ca.crt is refused instead of
# skipped: compose forces HTTP_PROXY through the proxy, so booting without
# the CA turns an ordering bug into cryptic x509 failures mid-deploy.
#
# Anchor dir and rebuild command are detected by capability, not distro id:
# * Debian/Ubuntu: /usr/local/share/ca-certificates (name must end in .crt),
# rebuilt by `update-ca-certificates`.
# * Arch and Fedora/CentOS both rebuild with `update-ca-trust extract` but
# read different anchor dirs, and with-ca-trust.sh creates both dirs on
# both families, so the anchor goes into each.
# Param: CA_ROOT prefix for every absolute path below; empty in production.
