From a7e29e608258e2a032e6aa45ea46d295254fed42 Mon Sep 17 00:00:00 2001 From: "Claude Sonnet 4.6" Date: Sun, 12 Apr 2026 03:29:22 +0000 Subject: [PATCH 1/4] feat: add lib.rs and fix rust-cache in CI workflows Split into lib + bin crate structure so core, cli, and mcp modules are available as a library for external crates. Also remove the incorrect `workspaces` parameter from Swatinem/rust-cache since this is a single crate, not a Cargo workspace.
