Complete Wipeout host model coverage

Maps the placement, display and clip-boundary fields with rectangular and
polygonal clip validation. staged_python_wipeout_lifecycle_over_real_ipc
passes the full gate including DWG and DXF reopen with re-edit.

 | Mesh | **Complete** | Writable: `blend_crease`, `subdivision_level`, `vertices`, `faces`, `edges` (start, end, optional crease), `override_option`; `version` is read-only. Host validation requires at least 3 finite vertices, faces of at least 3 in-range indices, edges with distinct in-range endpoints and a finite non-negative crease, and a non-negative subdivision level, so out-of-range topology is rejected before mutation. `staged_python_mesh_lifecycle_over_real_ipc` passes the full gate: a quad with a creased edge, an added vertex and triangle plus subdivision level 1 in one transaction, canvas wires, seven rejection cases plus an atomic rollback, DWG and DXF reopen with re-edit, and three-step undo/redo. |
 | Helix | **Integration-tested / blocked at W by acadrust (DXF handedness)** | Writable generating parameters: `axis_base_point`, `start_point`, `axis_vector`, `radius` (the top radius; the base radius is the start point's distance from the axis), `turns`, `turn_height`, `handedness`, `constraint`. Read-only: `spline`, `major_version`, `maintenance_version`. The host rebuilds the derived NURBS spline with OCS's own helix builder on every scripted create or parameter edit (`normalize_scripted_helix`), so the spline always matches the parameters. Host validation requires finite positive radius, turns and turn height, a nonzero axis and a start point off the axis. `staged_python_helix_lifecycle_over_real_ipc` (shared `run_mesh_lifecycle`) passes C/R/E/D/U/I/V/P: creation with a derived spline ending at z = turns × turn height, a turns and handedness edit that regenerates it, canvas wires, seven rejection cases plus an atomic rollback, DWG reopen and re-edit, DXF reopen and re-edit, and three-step undo/redo. **W blocker (engine, pinned by a canary assertion):** the DXF reader parses boolean group 290 as an `i16` and never applies it, so a clockwise helix reopens counter-clockwise from DXF while DWG keeps it. Not `Complete` until the reader is fixed. |
 | RasterImage | **Integration-tested** | Writable: `file_path` (creation only; a later change is rejected because the image definition owns it), `insertion_point`, `u_vector`, `v_vector` (world units per pixel), `flags`, `clipping_enabled`, `brightness`, `contrast`, `fade`, `clip_boundary`. Read-only: `size` (pixel size, taken from the file), `class_version`, `definition_handle`, `definition_reactor_handle`. Creating from a script requires a readable image file: the host reads its pixel size, creates the `ImageDefinition` object, links it, and sets `size` and a whole-image clip boundary from the file. Host validation requires finite, non-parallel `u`/`v` vectors, brightness/contrast/fade within 0..=100, known display flags, finite clip vertices, at least 2 clip vertices when clipping is enabled, and an existing definition. `staged_python_raster_image_lifecycle_over_real_ipc` (shared `run_mesh_lifecycle`, real PNG fixture) passes C/R/E/D/U/I/W/V/P inside OCS: creation with a host-made definition, placement/scale/brightness/contrast/fade and clip edit in one transaction, canvas wires, eight rejection cases plus an atomic rollback, DWG and DXF reopen with the definition link and file path intact, re-edit, and three-step undo/redo. **Why not `Complete`:** the host does not create an `ACAD_IMAGE_DICT` entry or `IMAGEDEF_REACTOR` for a scripted image, so other CAD applications may need to repair the linkage; that cannot be verified here. Editing an existing definition (file path, resolution) is out of scope. |

Read-only: `class_version`, `definition_handle`, `definition_reactor_handle`. Scripted creation matches OCS's native WIPEOUT command, which also leaves the definition link unset. Host validation requires finite non-parallel `u`/`v` vectors, a positive `size`, brightness/contrast/fade within 0..=100, known flags, finite clip vertices, exactly 2 vertices for a rectangular clip and at least 3 for a polygonal one. `staged_python_wipeout_lifecycle_over_real_ipc` (shared `run_mesh_lifecycle`) passes C/R/E/D/U/I/W/V/P: rectangular creation, a switch to a three-vertex polygonal inside-clip with a move in one transaction, canvas wires, eight rejection cases plus an atomic rollback, DWG and DXF reopen with re-edit, and three-step undo/redo. |
