PFCL for VS Code

Thin client for pfcl-lsp. Install the server first:

cargo install pfcl-lsp        # or: cargo build -p pfcl-lsp

Then set pfcl.serverPath if the binary is not on PATH.

Features (v0): load-pipeline diagnostics (parse + resolve) as you type, completion from the loaded catalog and file-local definitions, hover with signature, description, kind, and hash. Catalogs load from <workspace root>/catalog by default; override with pfcl.catalogDirs. Saving a .fn.yaml reloads the catalog.

Published to both the VS Code Marketplace and Open VSX.
