ansible-galaxy is not on the system PATH on figment — Semaphore manages
its own venv under /opt/semaphore/apps/ansible/<ver>/venv/bin/.
Discover the binary dynamically rather than relying on PATH.
- New tasks/collections.yml installs collections from defaults list
into /opt/semaphore/ansible-collections on the host
- semaphore.container.j2: bind-mounts that dir into the container at
/home/semaphore/.ansible/collections (read-only)
- defaults/main.yml: semaphore_collections_dir + semaphore_ansible_collections
list (containers.podman, effectivelywild.technitium_dns)
- main.yml: collections task wired in after semaphore.yml, before verify
- Collections survive container restarts/rebuilds without image changes
- Re-run with --tags collections to add new collections without full redeploy
