Add ready-made dynamic and sensor model catalog

[FlorianPfaff]

Summary

Adds a ready-made model catalog for common tracking workflows:

• linear kinematic transition matrices and models: constant velocity, constant acceleration, constant jerk
• integrated white-noise process covariances: acceleration, jerk, snap
• continuous-to-discrete LTI conversion with process-noise discretization
• Singer acceleration transition and process-noise model
• nonlinear motion models: coordinated turn, nearly coordinated turn, nearly constant speed, SE(2)-style unicycle, local SE(3) pose/twist
• sensor/measurement models: range-bearing, bearing-only, range-bearing-Doppler radar, TDOA, FDOA, and pinhole camera projection
• package-level exports through pyrecest.models
• regression tests for the model catalog

Tests

Not run in this environment. Suggested command:

python -m pytest tests/test_dynamic_models.py

Note: the branch is based on an earlier main commit and is behind current main by unrelated commits, but the diff is localized to src/pyrecest/models and tests/test_dynamic_models.py.
