feat: upgrade to donglora-client 0.2, simplify connection, fix org URLs

- Upgrade donglora-client from 0.1 to 0.2 (ping-on-connect validation)
- Remove manual mux/serial fallback and manual ping — handled by client now
- Fix repository/homepage URLs to github.com/donglora/bridge
- Fix README links to donglora GitHub org

 # Changelog
 
-## [0.2.3] - 2026-04-06
+## [0.3.0] - 2026-04-07
 
 ### Changed
 
-- README: clarify that the bridge relays raw LoRa packets and works with any
-  protocol (Meshtastic, MeshCore, etc.) simultaneously.
+- Upgraded to `donglora-client` 0.2: all connections now auto-validate via
+  ping-on-connect, rejecting non-DongLoRa serial devices within 200ms.
+- Simplified connection logic — removed manual mux/serial fallback and manual
+  ping; `donglora_client::connect()` handles the full fallback chain and
+  validation internally.
+- Config negotiation detects mux vs serial via transport type instead of
+  string comparison.
+
+### Fixed
+
+- Repository and homepage URLs now point to `github.com/donglora/bridge`
+  (was `swaits/donglora-bridge`).
+- README links updated to `donglora` GitHub org.

-**donglora-bridge** relays raw LoRa packets over the internet. Every packet your

-[MeshCore](https://github.com/rocketgithub/meshcore-firmware),
