v0.3.0: ECCO Support

Added

• Added the documentation file component-development-process.rst, outlining the recommended FMU development workflow, best practices, and the role of virtual derivatives.
• Added the example XML structures BouncingBallStructure.xml and ForcedOscillator6D.xml to showcase richer algorithm and ECCO configuration sections together with clarified causality definitions.

Changed

• Refined the existing FMU XML examples with explicit algorithm sections, ECCO configuration, and clearer variable linkage descriptions.
• Updated driving_force_fmu.py to support vectorized amplitudes, frequencies, and frequency sweeps, while improving type annotations and initialization semantics.
• Changed the upper bound for the height variable in bouncing_ball_3d.py to inches to align with the rest of the example unit system.

GitHub workflows

• Added Python 3.13 to the main CI matrix to ensure compatibility with the current stable release.
• Updated the future/experimental workflow to track Python 3.14 instead of 3.13 for forward-looking coverage.
