Merge eis into main, as prep for release 0.4.0

[ClaasRostock]

Merge eis into main, in order to subsequently publish release 0.4.0

Changes since 0.3.2 summarized in CHANGELOG.md as per below:

Breaking Changes

• src/component_model/utils/controls.py: Refactored Controls from a multi-variable container into per-variable Control objects with typed read/write access, and improved goal tracking so initial speed and acceleration are handled correctly when setting or changing goals.
• src/component_model/utils/analysis.py: Reworked sine fitting by moving the sine_fit() function from component_model.analytic into component_model.utils.analysis and expanding it to fit offset sine waves, detect cycles from maxima, support cosine-like starts, and return offset, amplitude, angular frequency, phase, and a reference mid-time.

Resolved

• Fixed coordinate transform handling for vectors pointing in the negative z-direction.

Changed

• Relaxed range compatibility checks for units and promoted scipy from a test-only dependency to a runtime package dependency, aligning dependencies with actual package usage.
• Cleaned up FMU test artifacts by removing generated FMU binaries from the examples folder, building FMUs into the test working directory instead, ignoring generated .dat files, and switching shared test fixtures to session scope.
• Added or updated tests for the new controls behavior, sine fitting, transform handling, and FMU build workflow.
• Included minor follow-up cleanup such as corrected example text typos, small README/docstring/formatting updates, and lockfile refreshes.
