Method detectShadowBuild

pkg/lsp/server.go:191–233

detectShadowBuild checks if a shadow build directory exists and is valid. Returns the shadow directory path if found, empty string otherwise. A valid shadow build has: shadow directory exists, contains go.mod, and shadow build is enabled in config.

(workspacePath string)
