draftwright v0.4.3

A trust and validation-throughput patch release. Whole-part hexagonal stock now receives its
manufacturing definition, assembly recognition no longer combines evidence across bodies, and
performance validation is both more stable and faster to run.

Added

• Whole-part regular hexagonal stock is recognised independently of an attached boss and
  dimensioned as HEX … A/F plus its axial length (#1082). In-plane rotation preserves the
  geometric across-flats size instead of substituting an orientation-dependent bounding-box
  width. Automatic and declared paths share the same compiler and placement machinery, while
  completeness lint distinguishes placed, authored-suppressed, dropped, missing, and ambiguous
  outcomes.

Fixed

• Slot and pocket patterns cannot group members from separate assembly bodies (#1073).
  Recognition carries solid ownership through grouping and fails closed when ownership is
  unavailable, preventing plausible-looking phantom patterns across disconnected parts.

• The annotation-obstacle performance guard uses deterministic work-count evidence instead of
  a wall-clock threshold (#1071). The regression test remains load-bearing under mutation but
  no longer flakes because of machine load or suite ordering.

Changed

• The post-merge slow tier distributes individual tests across workers (#1108), using
  pytest-xdist load scheduling after local benchmark evidence showed a material speed-up
  without weakening fixture coverage. Hosted slow validation remains the single post-merge gate.
