Shell env PATH was being overridden by process.env PATH in
applyProviderEnv, causing agent spawns to fail with ENOENT when the
daemon runs from the Tauri desktop app (minimal GUI PATH). Flip the
merge order so login shell env wins.
Add a Providers section to `paseo daemon status` that resolves each
agent binary (claude, codex, opencode) and runs --version using the
same applyProviderEnv environment the daemon uses to spawn agents.
