Setting AGENT_HOST to the host's real IP (e.g. 10.40.40.3) causes the agent
to try binding to that specific address inside the container, which fails with
'cannot assign requested address' because the container only has a Docker
bridge interface.
Without AGENT_HOST the agent binds to 0.0.0.0:9001 and Docker's port mapping
(-p 9001:9001) forwards traffic correctly. The TLSSkipVerify on the Portainer
registration already handles the bridge-IP cert mismatch.
Fixes: portainer_agent restart loop on snap-based Docker hosts.

ubuntu-server-01 (10.40.40.2) runs Portainer itself and is already
managed via local Docker socket (Portainer endpoint ID=3). Deploying
a Portainer Agent there is redundant and port 9001 binding fails.
Add portainer_skip_agent: true flag to the inventory and check it in
both Play 2 (deploy agent) and Play 3 (register endpoint) to exclude
the host from agent-based enrollment.

- Remove /var/lib/docker/volumes mount (fails on nested Docker hosts)
- Add AGENT_HOST env var so agent cert is valid for host's real IP
- Add TLSSkipVerify/TLSSkipClientVerify to Portainer endpoint registration
to handle existing agents with bridge-IP certs
- Remove final delegate_to: localhost (wait_for now runs on remote host)
- Add ignore_errors: true to agent deploy and enrollment tasks
- Guard existing_endpoints.json with | default([]) for failed API calls

- Play 3: Run Portainer API calls from remote hosts directly (no
delegate_to: localhost). Add validate_certs: false for self-signed cert.
- Play 4: Replace localhost file report with debug output using run_once.
No filesystem writes = no privilege escalation needed on the runner.

- Add ansible_become_pass to all hosts (sudo uses same password as SSH)
- Remove truenas-scale and vyos from children groups (no connection info)
- Add ansible.cfg: host_key_checking=False, become=False as default
- Add become: false to wait_for_connection to avoid sudo during SSH test

- Add become: false to Play 4 (report) to prevent sudo on Semaphore host
- Add become: false to all delegate_to: localhost tasks in Plays 2 & 3
- Update usage comment to reflect correct inventory path (inventory/hosts.yml)

- find_docker_enroll_portainer.yml: discover Docker hosts across all VLANs,
deploy Portainer Agent, register in Portainer, write discovery report
- inventory/hosts.yml: auto-generated from NetBox (31 hosts) + UniFi clients
(135 unmanaged hosts not in NetBox) across vlan1/vlan40/vlan20
