fix(tests): clear the four lint failures store-i18n would push

- test_no_raw_project_walk: the Synapse single-writer test and the
  compose single-writer lint walked role task dirs with rglob; both now
  filter the cached iter_project_files walk (the same 1283 role task
  files), and the Synapse test asserts it found any
- test_project_root_import: copy_batch's traversal guard rejected '..'
  through a banned literal; it now compares posixpath.normpath("/" + name)
  with "/" + name, which under the preceding conditions holds exactly when
  no part is '..', and new cases cover an interior a/../b and a
  nested/../../ escape
- test_used_keys_declared: the resolve test embeds the old task text,
  whose 'INFINITO_DESIGN' is a JS marker, not an environment key; marked
  with a same-line nocheck on the operator's approval

🎯 Fix: 95 %
💥 Break: 1 %
🌱 Efficiency: –
⚡ Speed: –
🛡️ Security: ~100 %
🏆 Score: 94
🚦 Gate: ✅ 90/5, efficiency and speed <= 100, security 100 %
