fix(security#321): path traversal guard in loadWorkspaceEnv (CWE-22)

CWE-22: Path traversal in loadWorkspaceEnv (org_helpers.go). A malicious org YAML setting filesDir to "../../../etc" caused filepath.Join to escape the org root and read an arbitrary .env file. Guard: resolveInsideRoot(orgBaseDir, filesDir) — already used at org_import.go:327 for the same ws.FilesDir input. On traversal rejection, log and return only the org-root env vars (silent — callers expect empty map on read failure). No caller changes needed. Tests: 6 new cases in org_path_test.go covering: - Normal load (org root + workspace override) - Traversal attempt rejected (../escape-target) - Deep traversal rejected (10× "../") - Empty filesDir loads org root only - Non-existent filesDir is silent no-op - Empty orgBaseDir returns empty map Fixes: #321 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
