Crate lspkit 

lspkit — generic Rust infrastructure for building LSP+MCP servers.

The headline contribution is EngineApi — the contract that an LSP backend and an MCP server both consume so live analysis state is computed once and vended two ways. See spec.md at the workspace root for the full behavioral contract.

This is the L0 toolkit crate ([CRATE-LAYOUT-LAYERS]). Its modules have no internal dependencies:

• config — layered TOML config loader.
• vfs — concurrent open-document store with position-encoding support.
• sidecar — framed-IPC transport and lifecycle for out-of-process backends.
• treesitter — parser trait and parse cache (treesitter feature).
