Adds ModelGeoref { ModelUnits units; Eigen::Matrix4d stage2_meters; bool
has_stage2; } and computeModelGeoref(file*) in Federation.{h,cpp}. The
helper reads the project length unit, IfcProjectedCRS.MapUnit, helmert
parameters and WCS, and reduces them to a metres-in/metres-out stage 2
matrix using the existing Geolocation + Unit primitives. When the model
has no IfcMapConversion it returns an identity stage_2 with has_stage2
== false, so the upload pipeline can branch cheaply.
SceneLoader::Model gains a cached ModelGeoref; SceneLoader::modelGeoref
(uint32_t mid) computes lazily on first call (returns nullptr when the
IFC file isn't available yet — happens on the sidecar-hit path before
the data-source thread populates the streamer) and serves from cache
afterwards.
Not yet consumed by the upload pipeline; that's the next commit.

The struct holds per-model bookkeeping; Model describes its contents
rather than its container relationship.

Sidecar hits skipped opening the underlying .rdb/.ifc, so ifcFile() was
null and the property panel only showed cached name/type/guid. Now, after
a sidecar hit, a background thread opens <stem>.rdb (preferred) or
<stem>.ifc and hands the file to GeometryStreamer via setIfcFile(), with
a dataSourceReady signal so the UI refreshes the current selection.
Gated behind a new AppSettings::loadDataSource toggle (default on) so
users can opt into geometry-only viewing; when off, the sidecar-hit
thread is skipped and the stream-path ifc_file_ is released after
the sidecar write completes.
Also adds *.ifcview to the Add Files dialog filter so a cache can be
opened directly without its source file present.

Previously readSidecar/writeSidecar were keyed on (path, file_size) with
staleness rejected at read time. Switch to pure path-stem keying: foo.ifc
and foo.ifcdb/ both resolve to foo.ifcview, so the same cache serves either
source format. Staleness is user-managed (delete the sidecar to force a
rebuild), which also lets sidecars be copied or moved independently of the
source.
v8 header drops the source_file_size field.

Handle streamer success, failure, and cancellation as distinct terminal states so failed or cancelled loads do not finalize as successful models. Clean up partial model/UI state in the full and minimal viewer apps when a load is cancelled or fails.
Generated with the assistance of an AI coding tool.
MainWindow and MinimalWindow each carried ~150 lines of mirrored
load-queue, sidecar-thread, streamer-wiring, and ID-rebase code. Lift
all of it into a SceneLoader QObject in the library; both apps now
consume it via signals. Sidecar writes stay on the full-app side since
they need the consumer's element metadata strings.
