Lets 'ssh <alias>' connect directly to user@host instead of retyping it —
especially useful once machines are reachable over NetBird/VPN and have
IPs that aren't worth memorizing.
- lib/common.sh: ssh_config_path/add_ssh_host_alias/list_ssh_host_aliases/
remove_ssh_host_alias helpers, operating on the invoking user's own
~/.ssh/config (not root's) with correct 700/600 permissions and ownership
- base.sh: after SSH key import, optionally add one or more Host aliases
interactively as part of the base install
- services/ssh-config.sh: new standalone service (sudo ./setup.sh ssh-config)
to list/add/remove aliases any time, independent of base install; follows
the existing non-Docker standalone-bootstrap pattern (see crowdsec.sh)
- setup.sh: ssh-config never shows [installed] since it's a repeatable
management tool, not a one-time install
- README: new 'SSH Host aliases' section, base row and wizard-flow step 1
updated, ssh-config added to the extras group and copiable service list
Verified end-to-end with a test harness: add with defaults, add with a
custom user/port, list (correct numbering), and remove-by-name preserving
the other entry and file permissions.
