test: rename TestBitVector directory to tests

Rename the test directory from TestBitVector to tests and update all path references across the codebase.

Summary of Changes:
1. Renamed Directory:
  - Rename TestBitVector/ to tests/ using git mv.
  - Relocate all test modules and input data files to tests/.

2. Updated Configuration & Path References:
  - Update testpaths = ["tests"] under [tool.pytest.ini_options] in pyproject.toml.
  - Update all hardcoded relative file paths from "TestBitVector/..." to "tests/..." in BitVector/BitVector.py.

Verification:
- uv run pytest executed cleanly with coverage reporting across all test suites in tests/.
- uv run pre-commit run --all-files passed 100% cleanly across all hooks.
- uv build verified that all test files under tests/ are properly included in the source distribution.
