Adds the structs that were briefly in src/ifcviewer/Federation.{h,cpp}
two commits ago, now folded into the merged Federation alongside the
file persistence layer:
- FederationConfig: federation-wide unit ({prefix, name}). Default
METRE; one-of an IfcSIUnit name with optional prefix or an
IfcConversionBasedUnit name.
- FederationOrigin: stage 3 — XYZ in federation unit + Z-rot.
Composes to R_z · T(-xyz_meters), nominating a point as origin.
- AFrame + ModelTransform: stage 4 intent — A (model project or
map unit, per a_frame), B and pivot (federation unit), full
intrinsic-XYZ Euler rotation in degrees.
- ModelUnits: per-model project_length_to_meters / map_unit_to_meters
cached at load time.
Free functions composeFederationOrigin and composeModelTransform
return Eigen::Matrix4d in metres. composeModelTransform takes the
model's stage-2 georef matrix so it can lift `a` into metres when
authored in ModelLocal.
Federation gains config_, origin_ members + setters that emit
dirtyChanged. Each Model carries a transform_intent. JSON I/O
emits config / origin always; transform_intent only when non-default.
Schema stays "ifcfed/1" — additive, optional, sane defaults.
Five new tests: round-trip of the new fields, default-omission
behaviour, two compose smoke tests for FederationOrigin, and one
verifying the "pivot at B preserves A→B" invariant of
composeModelTransform. All 36 ctest cases pass.

Move src/ifcviewer-full/Federation.{h,cpp} (and its tests) into
src/ifcviewer/ so the lib stays the single source of truth for the
federation data model. Restores the original "agnostic lib usable
from ifcviewer-full and ifcviewer-minimal alike" framing.
Drop the unused per-model transform[16] / has_transform field — it
was round-trip-only with no UI to author it, and is being replaced
by an intent-based ModelTransform in the next commit. No real
.ifcfed in the wild populated this field; old files still load
(unknown JSON keys ignored), they just lose the unused transform.
Replaces the pure-data-model Federation.{h,cpp} that was added a
few commits earlier — that file's structs and compose helpers
return as part of the merged Federation in commit 6.
ifcviewer-full's per-app tests dir is removed (test_federation was
the only one); BUILD_IFCVIEWER_TESTS now wires test_federation in
under src/ifcviewer/tests/, with the Qt6::Core/Gui/Test dependency
declared inline since unlike the other Tier-1 tests it has to pull
Qt in. All 31 tests pass.

FederationConfig holds the federation-wide display unit (defaults to
METRE; on load the first model's MapUnit becomes the default).
FederationOrigin captures stage 3 — XYZ in federation unit + Z-rot —
and composes to R_z · T(-xyz_meters), nominating a point as the new
origin and rotating around it. ModelTransform captures stage 4 —
A in model project or map unit (per AFrame), B and pivot in
federation unit, full intrinsic-XYZ Euler rotation — and composes to
T(B - R_pivot · A) · R_pivot, rotating first then translating so the
rotated A lands at B.
ModelUnits caches per-model project/map unit-to-metres scales so the
compose helpers don't need to re-read the IFC each call.
All composed matrices are in metres; user-typed numbers are stored
in source units to round-trip without precision loss, and converted
on compose via Unit.h.
Not yet wired into the streamer or .ifcfed I/O — pure data model and
maths, integrated in subsequent commits.
