hsiegeln c2efb7fbf7 fix(loader): chown /app/jars to loader so volume init gives wget write perms ...

Root cause of "Loader exited 1" with `wget: can't open '/app/jars/app.jar':
Permission denied`. DockerRuntimeOrchestrator creates a fresh named volume
per replica and mounts it RW at /app/jars. Docker initializes empty named
volumes from the image's mountpoint contents — but /app/jars didn't exist
in the loader image, so the volume came up as root:root 0755. Loader runs
as UID 1000 and can't write to a root-owned dir.

Pre-create /app/jars in the image owned by `loader`. Volume init now
inherits loader:loader ownership and wget writes app.jar successfully.
Verified locally with the full hardening contract (cap_drop ALL, readonly
rootfs, /tmp tmpfs, no-new-privileges, apparmor=docker-default).

This is the conditional CI build's first real exercise — the loader-build
step gated on cameleer-runtime-loader/** changes will fire on this push
and produce the fixed `:latest` tag.
