Plugins have no way to localize their own dialogs: the UI language lives in
OrcaSlicer.conf, which the plugin audit hook deny-lists because the file sits
next to cloud secrets. Add a read-only host accessor that returns just the
language code (current_language_code_safe), so plugins can match the app
language without touching the config file.
wx 3.3.2 delivers webview script messages synchronously inside the native
callback on GTK and macOS, so script plugins run with the plugins-dialog
webview's signal/delegate frame on the stack. Creating and presenting the
orca.host.ui window from there crashed on Linux at Raise() --
gtk_window_present while GTK's deferred show was still in flight.
Defer the whole window creation to a CallAfter with a pre-bound registry
handle (post/close stay FIFO-safe, teardown races become a no-op), and
drop Raise() plus the show_modeless_dialog wrapper: Show() already
activates and fronts a new window on every platform.

Bind libslic3r's TriangleMesh directly with a shared_ptr holder rather than
wrapping it in a HostTriangleMesh snapshot struct. ModelVolume.mesh() hands
out the volume's own shared_ptr (via const_pointer_cast, which only serves
the holder type), so the Python object pins the snapshot exactly as the
wrapper did, and the zero-copy views now use the Python object as their
array base — deleting the capsule machinery.
The wrapper's type-level constness becomes a documented rule instead:
handed-out meshes are copy-on-write snapshots shared across threads, so the
binding exposes only const methods; a future mutable-mesh API must operate
on plugin-owned copies handed back via ModelVolume::set_mesh.
No Python-visible change (orca.host.TriangleMesh, same methods/docstrings),
and plugins now hold the real class a future set_mesh() will accept.
Verified with slic3rutils and fff_print suites.
PluginHostApi.cpp had grown into one TU holding the module entry point plus
three unrelated domains (presets, model/mesh graph, app access), and
PluginHostSlicing.cpp mixed ownable geometry value types with the
non-owning live print graph. Reorganize the orca.host surface into
plugin/host/ with one registrar per domain:
- PluginHost.hpp/.cpp entry point (replaces PluginHostApi)
- PluginHostBindings.hpp internal per-domain registrar declarations
- PluginHostGeometry.cpp BoundingBox, Point, Polygon, ExPolygon + ndarray parsing
- PluginHostMesh.hpp/.cpp TriangleMesh snapshot (own TU ahead of planned
mesh construct/mutate APIs)
- PluginHostPresets.cpp Preset, PresetCollection, PresetBundle
- PluginHostModel.cpp scene graph: Model, ModelObject, ModelInstance, ModelVolume
- PluginHostApp.cpp Plater + plater()/model()/preset_bundle() accessors
- PluginHostSlicing.cpp live print graph only, now with a single lifetime story
- PluginHostUi.hpp/.cpp moved unchanged
PluginBindingUtils.hpp stays at plugin/ root: it is shared with pluginTypes/
and tests, not host/-specific.
No Python-visible change: same submodules, class names and docstrings.
Verified with slic3rutils and fff_print suites.
