-The extension uses a caching mechanism to improve performance when analyzing module dependencies:

-- Cache files are stored in the extension's global storage area:
-  - macOS: `~/Library/Application Support/Code/User/globalStorage/mununki.vscode-bibimbob/cache`
-  - Linux: `~/.config/Code/User/globalStorage/mununki.vscode-bibimbob/cache`
-- Each workspace gets its own cache file based on the workspace name
-- The cache is automatically invalidated when module files change (using digest comparison)
-- You can manually clear the cache using the "ReScript: Clear Dependency Cache" command
