[PabloScolpino]

• Version iTerm2 config plist and link it in setup
• Fix Ansible playbook conditions to use ansible_os_family instead of ansible_distribution (supports Linux Mint and other Debian derivatives)
• Add lrt alias (eza sort by modified)
• Set SSH_AUTH_SOCK for 1Password agent
• Unset GEM_HOME to fix tmuxinator env pollution
• Make git config idempotent (skip if already configured)
• Add herb_ls to nvim LSP servers
• Lazy-load Telescope via cmd
