TypeScript/Deno runtime bridge — Go gRPC server + Deno sidecar. The seed project that inspired the entire Core framework. - Module: forge.lthn.ai/core/ts - Package: ts (renamed from coredeno) - gRPC bridge: CoreService (Go→Deno) + DenoService (Deno→Go) - Deno runtime: worker isolation, module loading, permissions - Proto descriptor retains original path (regenerate with protoc later) Co-Authored-By: Virgil <virgil@lethean.io>
