fix(acp_server_opencode): detect opencode CLI at deploy time (portable across Debian/Ubuntu/macOS) (#22)

Stop assuming a fixed opencode path. Probe the real binary with 'command -v'
using the role PATH, then feed the resolved path to both the systemd unit and
the launchd plist (plist now also passes -opencode-bin). Falls back to the
OS-aware default when opencode is not yet installed.

Also remove the dead acp-bridge.service.j2 template: it was not deployed by any
task and referenced two undefined vars (acp_opencode_bridge_disabled_binary_path,
acp_opencode_bridge_opencode_binary_path) — a hardcoding landmine.
