Module workspace 

Workspace file discovery and @import closure construction (ADR-0091).

Each open editor buffer is analyzed as its own compilation root: the LSP parses it, walks for @import("...") calls, transitively loads every reachable file (open buffer first, on-disk fallback), and hands the closure to the frontend as a single CompilationUnit. Unrelated files in the workspace are never merged together — that’s what kept opening this very repo from producing thousands of fn main() duplicate-definition errors before ADR-0091’s per-root revision (2026-05-19).

Functions

build_root_closure

Build a (root + transitively-@import-reachable) WorkspaceFile set for one compilation root.

enumerate_gruel_files

Enumerate every *.gruel file under root, respecting .gitignore and skipping .git/target.
