Introduces a new optimization engine that analyzes each layer's geometry and dynamically adjusts print parameters (nozzle temperature, speed, flow rate, fan speed) on a per-layer basis for stronger parts with minimal failure risk.

Key components:

LayerAnalyzer: Computes per-layer geometry metrics (cross-section area, overhang fraction, thermal mass, bridge detection, feature width)
AutoSliceOptimizer: Multi-pass optimization engine that computes temperature, speed, flow, and cooling adjustments based on geometry analysis, material properties, and machine capabilities
Integration into GCode pipeline via M104/M106/M220/M221 commands
Two new config options: auto_slice_optimization (bool) and auto_slice_quality_target (0.0-1.0 quality vs speed tradeoff)

The optimizer considers: thermal load from part geometry, overhang quality, bridge solidification, small feature preservation, chamber temperature compensation, volumetric flow limits, and minimum layer cooling time.
