v0.12.1

Breaking changes

• Removed machining terminology from the geo layer — several functions
  and parameters renamed to use geometry-domain names:
  • trochoid_along_3d: tool_diameter → diameter
  • ClearedArea.expand: tool_path → path, tool_radius → radius
  • MedialAxis.compute: tool_radius → min_clearance
  • offset.find_deepest_cores: valid_tool_area → regions
• append_end_fillets: the single side parameter is split into
  start_side and end_side, fixing fillet direction at V-junctions

New features

• descending_radius_fillet — new fillet function that tries descending
  radii until one fits, replacing the manual trim_to_safe_fillet_span /
  try_fillet_one_end cascade
• cut_power parameter on adaptive_entry, adaptive_peeling,
  adaptive_wavefronts, and link_arcs_to_ops for laser power control
• PyWavefrontGraph gains segments, segment_directions, and
  arc_segments properties exposing V-junction-split sub-segments

Bug fixes

• Fix duplicate cutlines emitted by split_ordered_wavefronts
• Fix wrong fillet direction on arcs with V-junctions (split arcs before
  determining turn sign so each half gets its own direction)
• Fix adaptive peeling corner coverage — all bites now incorporated
  unconditionally, with a perimeter fallback when find_cutting_arc fails
• Fix CDT panics from degenerate geometry and peeling hangs on pinched
  frontiers
• Fix link_arcs_to_ops MAT reconstruction when passed raw (nodes, edges)
