Created setup_intercom_simple.sh using talkiepi (barnard fork) instead of
talkkonnect for a more stable and lightweight intercom solution.
Advantages over talkkonnect:
- Simpler build process (no Opus patching required)
- Fewer dependencies (just Go, libopenal, libopus)
- Full CLI support for server, username, password, and channel
- More stable and less fragile
- Better suited for headless/kiosk automation
Also added INTERCOM_COMPARISON.md documenting all evaluated options
(talkkonnect, talkiepi, barnard, mumbler) with recommendations.
