WS bridge 0.6.0

Self-contained Go build of the WebSocket-to-TCP bridge from
tools/ws_bridge.go (v0.6.0).
No Python, no pip install, no runtime dependencies.

Pick your platform:

• ws_bridge-*-windows-amd64.exe — Windows 10/11 64-bit
• ws_bridge-*-linux-amd64 — Linux 64-bit
• ws_bridge-*-darwin-arm64 — macOS Apple Silicon

Run: open a terminal in the download folder and execute
the binary. Defaults to listening on ws://localhost:7878;
see --bind and --port for overrides. The Reticulum
daemon target (host:port) is supplied per-connection by
the webapp via ?host=X&port=Y query params, not as a CLI
flag — one running bridge can serve any number of webapp
instances against any number of different rnsds.
