Master vault password is fetched from Vaultwarden via the rbw agent
(scripts/vault-pass-client.sh, wired as vault_password_file) instead of a
plaintext .vault_pass. Vault secrets use a nested vault.<service>.<key> map.
Encrypted vault.yml files are excluded from lint. Includes the host rename in
Makefile and STATUS.md.
