tegwick 30a3f908aa feat(custodian-agent): Ansible role + Makefile for Custodian SSH identity
Establishes a dedicated SSH keypair for the Custodian automation agent:
- ansible/roles/custodian_agent/: authorized_key task (tagged custodian_agent)
- ansible/inventory/group_vars/all.yaml: custodian_agent_user/pubkey vars
- ansible/playbooks/bootstrap.yaml: custodian_agent role added
- Makefile: provision-custodian-agent / provision-custodian-agent-host targets

Keypair generation: cd ~/the-custodian && make custodian-keygen
Then deploy:        cd ~/railiance-infra && make provision-custodian-agent

The private key lives at ~/.ssh/id_custodian_agent — never committed.

# custodian_agent role — injects the Custodian automation SSH identity
#
# What it does:
# - Ensures the target user (custodian_agent_user) exists
# - Adds custodian_agent_pubkey to that user's authorized_keys
# - Restricts the key: no X11, no port-forward, no pty for non-interactive use
#
# Variables (set in group_vars/all.yaml or pass via --extra-vars):
# custodian_agent_user: user account the key is added to (default: tegwick)
# custodian_agent_pubkey: the public key string (required, set in all.yaml)
#
# The private key lives on the workstation at ~/.ssh/id_custodian_agent.
# It is NEVER committed to any repository.
