Addresses the first codex review of the binary `.fig` parser.
BLOCKs:
- kiwi: 64-bit varint now uses Kiwi's terminal-byte rule (eight
7-bit groups then a final full-8-bit byte) — the old `& 127` mask
on every byte corrupted u64 values above 2^56.
- kiwi: an invalid schema definition kind (> 2) is now rejected
instead of silently treated as a message.
- kiwi: array decode rejects a length exceeding the buffer size —
guards against a hostile zero-byte-element array spinning the
decode loop billions of times.
- zip_reader: aggregate 2 GiB decompression budget + 10k entry cap
on top of the existing per-entry limit (zip-bomb defence).
CONCERNs:
- detect_kind now recognises the `PK\x03\x04` ZIP magic as Binary —
the common Figma export form (`canvas.fig` + `images/` in a ZIP)
was being rejected before container.rs could unwrap it.
- resolve_style_references now also resolves style refs inside
instance `symbolData.symbolOverrides` entries.
- kiwi: enum field type codes are no longer resolved (unused; kiwi
writes 0) so a stray code can't reject a valid schema.
Plus a zip-wrapped end-to-end test + the misleading zstd test rename.
op-figma 84 tests green (+1); clean build.

Stage G — the binary `.fig` parser is now end-to-end functional;
`parse_fig` no longer returns NotYetImplemented for binary input.
- image_resolver.rs: resolve_image_blobs walks the converted document
and replaces `__blob:N` / `__hash:HEX` image-fill placeholders with
base64 `data:` URLs (MIME sniffed from magic bytes).
- lib.rs: new `parse_fig_binary(bytes, name, layout_mode) -> FigImport`
runs the whole pipeline — container split → Kiwi decode → tree
build → node conversion → image resolution. `parse_fig`'s Binary
arm delegates to it; `FigParseError::NotYetImplemented` retired in
favour of `Binary(String)`. Entry points re-exported.
- binary_e2e_tests.rs: assembles a real fig-kiwi container from
scratch (hand-built Kiwi schema + data chunks, deflate-compressed)
and asserts the full pipeline yields a PenDocument with the
rectangle at the right position/size + canonical-JSON round-trip.
op-figma 83 tests green (+6); clean build, no warnings.
Closes the §2.1 P0 gap — Figma binary `.fig` parsing.
