Fix Tailscale peer detection by parsing text output

Replace JSON parsing with simpler text output parsing from tailscale
status command. The text format clearly shows hostname and connection
method (direct/relay/idle) making detection more reliable.

Fixes issues with incorrect hostname (localhost instead of actual name)
and incorrect connection method detection (showing relay when actually
using direct connection).
