Release Relay connector 0.1.3

[Raphjacksun7]

Purpose

Update the shared Relay Connector for PocketStation 1.1.6 and use the route settings and execution safety names throughout its Rust API and guide.

Product result

pks and native SDK bindings continue to share one Relay WebRTC, Opus, and RTP implementation. Audio publication, named buses, output cancellation, and shutdown behavior are unchanged.

Verification

• 33 package tests pass.
• Portable Connector semantics pass.
• Strict Clippy passes.
• Rustdoc passes with warnings denied.
• cargo package -p pocketstation-relay --locked builds and verifies against the published Core 1.1.6 crate.

Evidence limits

No new WAN, TURN, physical-device, browser, or latency claim is introduced. No scaffold or mock was added.
