CHANGELOG highlights

Added

• Configurable supportGap (PR Add support configuration options: supportGap, supportDensity, and tree support settings #189) — shared by normal and tree support; replaces the previously hardcoded nozzleDiameter / 2 lateral gap. Default 0.2 mm preserves existing behaviour.
• Configurable supportDensity (PR Add support configuration options: supportGap, supportDensity, and tree support settings #189) — normal support grid density as a percentage (0–100). Default 50 matches the previously hardcoded spacing equivalent; 0 short-circuits to no support lines.
• Configurable supportRootsEnabled (PR Add support configuration options: supportGap, supportDensity, and tree support settings #189) — boolean toggle for tree-support root structures. Default true.
• Configurable supportRootCount (PR Add support configuration options: supportGap, supportDensity, and tree support settings #189) — number of radial roots at the trunk base (1–8). Default 4.
• Configurable supportBranchAngle (PR Add support configuration options: supportGap, supportDensity, and tree support settings #189) — angle (degrees, (0°, 90°)) of branches rising from the trunk. Default 45.
• Configurable supportTwigAngle (PR Add support configuration options: supportGap, supportDensity, and tree support settings #189) — angle (degrees, (0°, 90°)) of twigs rising from branch nodes to contact tips. Default 45.

All six options default to the values previously hardcoded, so no existing behaviour is affected.

three is listed as a dependency at ^0.184.0, but peerDependencies.three is still ^0.183.2 (which excludes 0.184.x). This will trigger peer dependency conflicts for consumers (and can fail installs with strict peer dep resolution). Update the peerDependencies range for three to include 0.184.x (e.g., align it with the dependency), and regenerate package-lock.json accordingly.
