zsh: guard optional tool sources; fix tailscale ProxyCommand path
Source cargo, deno, homebrew, and orbstack env files conditionally so
missing installs don't cause errors on any host.
Fix SSH ProxyCommand on macOS to use the absolute Tailscale.app binary
path — ProxyCommand runs with a minimal environment so Homebrew PATH
isn't available.
