* fix(export): prevent GUID collisions and file corruption on .fig round-trip
Nodes sharing the same imported source.id (component instance children,
cloned subtrees) silently overwrote each other on export because the
GUID assignment reused imported GUID values without checking for
duplicates. This caused data loss on reimport — only the last node
with a given GUID survived.
- Track all assigned GUID values in a Set for O(1) collision detection.
- Scan imported source.ids for both sessionID 0 and 1 before assigning
any new GUIDs, so the counter starts past every imported value.
- Fall back to counter-based GUIDs when source.id collides with an
already-assigned value.
Additional fixes in the same change set:
- cloneTree now deep-copies source.fig via structuredClone, preventing
mutations on a clone from corrupting the original node's kiwi payload.
- Removed decompressFigKiwiData sync wrapper (zero callers) and the
silent try/catch fallback in parseFigKiwiContainer that masked
corrupt data as raw bytes.
- buildFigKiwi uses Bun.zstdCompressSync when available, matching the
zstd decompression path already used on import.
- Fixed setSavedVersion ordering in read.ts — must run after
requestRender to capture the post-bump version, preventing spurious
dirty-state immediately after file reload.
Tests: GUID collision (2 and 3 node), clone isolation, parse failure,
text export zstd compatibility, gold-preview round-trip.
* fix(export): handle EXCLUDE boolean operation and BOOLEAN_OPERATION node type
The internal representation uses EXCLUDE for exclude boolean operations,
but Figma's kiwi schema uses XOR. Map EXCLUDE back to XOR on export so
round-trips through .fig files don't fail. Also add BOOLEAN_OPERATION to
VALID_NODE_TYPES and increase timeout for heavy material3 fixture test.

* fix(clipboard): detect zstd-compressed data before zlib inflate
fflate's inflateSync silently accepts zstd-compressed data and returns
garbage instead of throwing. Check for the zstd magic bytes (28 b5 2f
fd) before attempting zlib decompression. Also revert the EXCLUDE enum
addition to the kiwi schema since the export-node.ts mapping is
sufficient.

* test(scene-graph): group clone regression coverage
* ci: retrigger CI checks
* test: increase timeouts for heavy .fig fixture tests on slow CI runners
Gold-preview.fig and material3.fig parsing/export tests consistently
exceed the 5s bun:test default timeout on GitHub Actions runners.
Increase to 30s for: beforeAll codec init, clipboard roundtrip,
glyph blob roundtrip, group reclassification, and text measurement.
* test: add individual test timeouts for heavy .fig fixture tests
The beforeAll timeout helped but individual test() calls also need
explicit 30s timeouts since bun:test applies the 5s default per-test.
Fixes remaining CI flakes in glyph-blob roundtrip and clipboard
roundtrip tests.
* test: increase beforeAll timeout for render cache test
The canvas/render cache test loads gold-preview.fig AND initializes
CanvasKit (Skia WASM), which is much slower than the other fixture
tests. Use 60s timeout to account for slow CI runners.
* fix(export): reserve document GUID to prevent 0:0 namespace collision
- Add docGuid (0:0) to assignedGuidValues before processing imported
node source.ids, preventing an imported node with source.id "0:0"
from reusing the document's GUID slot
- Add regression test using session-0 source.ids to verify nodes
survive roundtrip without document GUID collision
- Remove unnecessary async keyword from synchronous component
metadata test
* fix(export): guard canvas GUID reuse with assignedGuidValues check
- Mirror getOrCreateNodeGuid() collision logic in buildCanvasEntries():
if an imported page's source.id maps to a GUID already in
assignedGuidValues, generate a fresh counter-based GUID instead
- Prevents canvas-level last-write-wins when multiple pages share
the same source.id or a page uses 0:0
* fix(test): use explicit little-endian writes and fix misleading test title
- Replace host-endian Uint32Array writes with DataView.setUint32(offset, value, true) in parse-failures.test.ts to ensure platform-independent fig-kiwi container assembly
- Rename test title from "clone clears source.id from the original" to "clone clears source.id from the clone" to accurately reflect what the assertions verify
* test(io): use file-level timeout for heavy fixture

Port the timeout fixes from PR #351 that resolved the unit-test CI
timeouts. Add HEAVY_TEST_TIMEOUT_MS (30s) in tests/helpers/test-utils.ts
and apply it to the slow gold-preview.fig fixture tests/hooks:
- clipboard roundtrip
- group reclassification
- glyph blob preservation
- auto-layout text measurement
- render/canvas/cache
- Update EffectType schema assertion for modern Figma enum values
- Treat unsupported OpenType font buffers as unavailable
- Skip CJK outline fallback coverage when the LFS font fixture is not materialized
- Use container bounds for stroked frames with drop shadows
- Keep stroke-geometry shadows for childless stroke-only shapes
- Cover the shadcn dropdown menu case
- Keep explicit color filter deletion checks compatible with cleanup guards
- Verify text inner-shadow restore balancing through the restore-count loop
