feat: added hypothesis and pytest-benchmark to tests/requirements.txt

[S1DDHEY]

Description

Problem or Issue being addressed

The test suite currently relies entirely on hand-crafted fixtures and test vectors. There is no property-based testing framework or benchmarking harness available for contributors to use. This is a prerequisite for introducing property-based test coverage for critical modules like PSBTParser, DecodeQR, and embit_utils.

Solution

Added hypothesis==6.151.10 and pytest-benchmark==5.2.3 to tests/requirements.txt, following the existing convention of pinning exact versions. Both packages integrate cleanly with the existing pytest==7.4.2 setup and introduce no regressions, all 145 existing tests continue to pass.

Additional Information

This lays the groundwork for future PRs that will introduce Hypothesis strategies for PSBT and QR decode testing.

I have reviewed these notes:

• Keep your changes limited in scope.
• If you uncover other issues or improvements along the way, ideally submit those as a separate PR.
• The more complicated the PR, the harder it is to review, test, and merge.
• We appreciate your efforts, but we're a small team of volunteers so PR review can be a very slow process.
• Please only "@" mention a contributor if their input is truly needed to enable further progress.

• I understand
