Rewrote project-switch entirely from TypeScript to Rust. The Node.js version had noticeable startup latency (~100-200ms) which felt sluggish for something that should be instant. The Rust version starts in under 5ms.

Ported all four subcommands (switch, add, current, open) to Rust using clap for argument parsing, serde_yaml for config file handling, and inquire for interactive prompts. The config format stays the same — ~/.project-switch.yml with projects, commands, and browser overrides — so it’s a drop-in replacement.

Set up a Docker-based cross-compilation pipeline that builds both Windows and Linux binaries from a single docker-compose up build command, using gcc-mingw-w64 for the Windows target.
