tsc-rs (ts-rust): complete TypeScript compiler and LSP rewritten in Rust

The project author announced tsc-rs (ts-rust), a complete TypeScript compiler, type checker and LSP rewritten in Rust, now open source and drop-in replaceable for tsc. Development took five months; about $400,000 was spent unsuccessfully on Codex tokens, then $20,000 on Opus tokens, and progress was made in two weeks. The tool’s availability potentially offers an alternative within the TypeScript ecosystem.
