mc#786: parseEnvFile(filepath.Join(orgBaseDir, ws.FilesDir, ".env")) was called
without the resolveInsideRoot path-traversal guard. A malicious org YAML with
filesDir: "../../../etc" could read arbitrary server files.
Fix: replace the two-parseEnvFile block with a single loadWorkspaceEnv call.
loadWorkspaceEnv already applies resolveInsideRoot to ws.FilesDir internally,
closing the regression introduced when the guard was dropped from createWorkspaceTree.
Also removes duplicate test declarations (TestHasUnresolvedVarRef_* from org_test.go
and TestExtractResponseText_ResultNotMap from delegation_test.go) that blocked
go build — the comprehensive versions live in *_pure_test.go / *_extract_response_text_test.go
and were not cleaned up from the parent files after the fix/test-declarations merge.
