Rust Glancer: Rust LSP using 100x less RAM

Rust Glancer is a Rust language server that targets under 100 MB RAM for typical projects by storing a frozen analysis on disk and loading data only when needed, enabling instant reuse after editor restarts. It provides full indexing with type inference, a Chalk-based trait solver, and supports common LSP features such as go-to-definition, hover, inlay hints, and completions, though many advanced capabilities remain unimplemented.
