bd57cc873 shifted the directrix curve by -mean before sweeping, then
translated the result by -mean again instead of +mean, placing the
geometry at original - 2*mean. Negating the restore translation fixes
the position; shape size was unaffected.

ItemIsASum and Quantities are exporter columns that were missing from
MAIN_CSV_HEADER_COLUMNS, causing them to be misidentified as numeric cost
value categories on re-import. Also initialise rate_cost_schedule to None
before the search loop to avoid UnboundLocalError when no match is found.

Contexts were deleted with remove_deep2 into a single set, but
file.add() inflates inverse counts causing phantom references. Split
into coord_ops (0 real inverses, remove_deep2 recurses to clean
IfcProjectedCRS) and contexts (sorted parent-first so phantoms don't
become dangling references). Remove stale MakeVolume stub from
ifcopenshell_wrapper.pyi.

Don't leave a broken repo if ifcmerge is misinstalled.
Fix bug where only local branches could be merged.
Fix gitch where merge commits were not considered relevant.
Add update callbacks to the relating_object and related_object
PointerProperties so that selecting an object via the eyedropper
in BIM_PT_aggregate immediately calls aggregate_assign_object
and closes the editing panel, removing the need to click the
checkmark button manually.

Adds `remove_coplanar_boundary_lines()` to operator.py (Bonsai uses this
path, not draw.py's main()). After `merge_linework_and_add_metadata()`
assigns material CSS classes, this post-processes the SVG to delete
projection line segments that appear in two or more adjacent, coplanar
elements with the same material and presentation style.
Key design decisions:
- Material identity: compared via sorted IFC material ID tuples from
`get_materials()`, not CSS class names — avoids false matches between
unrelated `material-null` elements.
- Presentation style identity: compared via IFC IfcPresentationStyle IDs
from `StyledByItem` on geometry representation items — handles elements
with no material but distinct visual styles.
- Physical adjacency: confirmed by a 3D shared-vertex test (tol=0.01 m)
after a quick AABB guard, rejecting elements whose 2D projections
overlap but sit at different depths.
- Coplanarity: determined by the dominant (largest-area) face normal of
each Blender mesh object — area-weighted averages are unreliable for
slabs whose equal top/bottom faces cancel out. Folded walls sharing an
edge but meeting at an angle are correctly rejected (normal dot ≪ 1.0).

- Add Anthropic prompt caching (cache_control on system prompt and
tools) to reduce repeated token costs by ~90%
- Truncate large tool results in conversation history (2000 char cap)
to prevent context bloat from ifc_tree/ifc_select responses
- Add sliding window (40 messages) on conversation history, trimming
at user message boundaries to avoid breaking tool-call sequences
- Default "New IFC" button to IFC4X3 schema instead of IFC4
- Constrain ifc_new schema parameter with enum to prevent invalid
schema strings like "IFC4X3ADD2"

Parse ifcmerge JSON output and display a per-conflict breakdown in the
panel when merge fails. Ctrl+click on the Merge button previews
conflicts without committing. Add SelectConflictEntity operator to
select and frame the conflicting object in the 3D viewport.

A degenerate edge (zero-length segment) caused an early `return`
of a tuple instead of continuing the loop, resulting in a
TypeError when snap.py iterated the result and tried to assign
`point["group"]` on a float.

Add a provider selector (OpenAI / Anthropic) to the ifcchat web UI,
allowing users to use their Anthropic API key with Claude models
instead of only OpenAI.
