v0.46.0 - Internal improvements

Breaking Changes

• Test Helper Imports Refactored: Direct imports from libtmux.test are no longer possible. You must now import from specific submodules (#580)

  # Before:
  from libtmux.test import namer
  # After: 
  from libtmux.test.named import namer

  # Before:
  from libtmux.test import RETRY_INTERVAL_SECONDS
  # After: 
  from libtmux.test.constants import RETRY_INTERVAL_SECONDS

Internal Improvements

• Enhanced Test Utilities: The EnvironmentVarGuard now handles variable cleanup more reliably
• Comprehensive Test Coverage: Added test suites for constants and environment utilities
• Code Quality: Added proper coverage markers to exclude type checking blocks from coverage reports
• Documentation: Improved docstrings and examples in the random module

These changes improve maintainability of test helpers both internally and for downstream packages that depend on libtmux.

What's Changed

• Coverage: Test helpers by @tony in #580
