Make test dummy txid hex a const
Make the existing dummy txid a constant so that it can be used in
additional tests.
What changed, and why it matters
This commit is a minor internal test cleanup. It moves a hard-coded dummy transaction ID string used only in unit tests into a constant so it can be reused in future tests. There is no change to production code, no security fix, and no user-facing behavior change.
No security action needed. Treat as normal code-quality/test-maintenance change.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The patch refactors test-only code in primitives/src/hash_types/mod.rs. It extracts the existing dummy Txid hex literal into a module-level const DUMMY_TXID_HEX_STR and updates the dummy_test_case helper to use that constant. The change is gated behind #[cfg(feature = “serde”)] and affects only test helpers; no runtime logic, parsing, serialization, or public API is changed.
