test(org-import): add _Pure test suite for sanitizeEnvMembers, flattenAndSortRequirements, collectOrgEnv edge cases

Adds 24 test cases covering:
- envRequirementKey: permutation invariance, dedup via sort
- sanitizeEnvMembers: digit-prefix, empty-string silence, all-invalid
- flattenAndSortRequirements: determinism, all-singles, groups-sorted-by-key
- collectOrgEnv: recursive children, rec-dedup-by-strict, strict-drops-any-of
- countWorkspaces: empty/flat/nested

All _Pure-suffixed to avoid collision with org_import_helpers_test.go names.
