Kayshen-X 75ec668463 feat(sdk): add op-web-sdk read-only web viewer crate
Plan 1 of the web embedding SDK (TS-retirement Phase 2): a wasm Viewer that
parses a .op document, renders it read-only via CanvasKit by reusing
op-editor-ui's canvas_viewport, supports pan/zoom navigation, exposes
read-only JSON snapshots, and exports SVG. Type-gen reuses jian-ops-schema's
ts-rs export.

Additive: new crate plus surgical cold pub exposures (CanvasViewport::from_scene
in op-editor-ui; pub mod canvaskit + pub init_backend in op-host-web). No TS
deleted. 17 tests; wasm 2.2 MiB gzip (0 env.* imports); clippy -D warnings clean.

# tools/check-widget-boundary.sh — Step 1b §1.4 widget boundary invariant.
#
# Per spec §1.4: widget logic (Widget impls, layout/paint/access_node)
# lives in `crates/op-editor-ui/src/widgets/` (Phase 7 reorg moved it
# out of the old openpencil-shell-core). The op-host-web crate's
# widget glue is scoped to a single module — `widget_host.rs` plus
# its sibling submodules under `widget_host/` (spec amendment
# 2026-05-11: the original "one file" constraint conflicted with
# the 800-line file cap once the host grew real keyboard /
# clipboard / paint coordination, so the module is now allowed to
# span multiple sibling files inside the `widget_host/` directory).
# The `// glue:` marker on the paint signature is still the only
# `fn paint(` allowed to drive widgets from this crate.
# Any function or file in op-host-web that pulls
# `op_editor_ui::widgets::*` must live in the widget_host
# module (the spec's "any function pulling the widget facade" clause).
#
# Reverse direction: op-editor-ui/src/widgets/ MUST contain the remaining
# OP-owned primitive impl files (tree, prop_row, text_input) AND each file must
# carry a real `impl Widget for X` — a stale file with the impl
# removed must not silently pass. (Phase 7.3 reorg: the
# openpencil-shell-core re-export shim was dissolved; op-host-web
# now pulls `op_editor_ui::widgets` directly from the real source
# crate, so the forward F4 path is unchanged.)
#
# Exit semantics:
# 0 PASS — both invariants hold.
# 1 FAIL — widget logic leaked into op-host-web OR the
# op-editor-ui widget impl files are missing / empty.
