fix(deps): replace step-security/retry and update action pins (#468)

* fix(deps): replace step-security/retry with nick-fields/retry

* chore(deps): update github action sha pins via pinact

* refactor: remove common-retry references from tests and validators

* chore: simplify description fallback and update action count

* docs: remove hardcoded test counts from memory and docs

Replace exact "769 tests" references with qualitative language
so these files don't go stale as test count grows.
