feat: IFC → Pascal converter (package + app)

Brings the IFC-to-Pascal converter into the monorepo as a pure-logic package plus a Next.js app, replacing the standalone repo that consumed published @pascal-app/* packages (and drifted from their schemas). packages/ifc-converter — pure conversion. Parses IFC via web-ifc and maps elements onto @pascal-app/core node schemas (workspace-linked, so no more version drift). Builds doors/windows, walls, slabs, columns, roofs, stairs, sites/buildings/levels. Validates each node via the real Zod schemas at build time (tryParse) and strips undefined metadata. apps/ifc-converter — the UI: drop zone, example picker, element search, JSON download, and a 3D preview rendered through the real @pascal-app/viewer (registry bootstrap + read-only scene) with a custom toolbar (camera/level/wall/grid/theme), level selector with camera-focus, auto-fit, and selection bridged to an inspector. Conversion specifics worth noting: - Door/window vertical centering (height/2; windows + sill). - Nearest-wall hosting fallback for files lacking IFCRELFILLSELEMENT, preferring walls long enough to contain the opening and clamping the along-wall position so cutouts can't overflow and break wall CSG. - Plain IFCWALL (Brep/mapped geometry) falls back to default height/thickness instead of collapsing to zero-height slivers. - Columns convert as plain structural shafts (no decorative base/capital) sized from the IFC profile. - Beams + items are skipped for now (no Pascal beam type; items need a catalog asset) — counted in the conversion summary. Large example IFCs are fetched from a public bucket at runtime; the four small ones are committed. web-ifc.wasm is copied into public/ on install/dev/build. README flags early-alpha + invites contributions. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
