fix: bind and link address now agree when --host is omitted
Summary
Config::bind_host()now binds0.0.0.0when--hostis omitted and a LAN IP can be auto-detected, so the address advertised in thetg://link (link_host()) is actually reachable instead of only bindable on loopback. Explicit--hostis still respected exactly as before.- Startup banner now prints the crate version (
tg-ws-proxy-rs vX.Y.Z), addressing the secondary request in the issue. - Added
AGENTS.mddocumenting the project layout and conventions for coding agents. - Bumped
Cargo.toml/Cargo.lockto 1.6.3 (required by CI's version-bump check).
