aiongg c52c6f3ec0 Merge upstream main into print-color
- hayro-syntax ascii_85.rs: main's decode-limit version (same bound as
  the pdfcraft ec0a965 copy, plus its test).
- hayro-interpret and krilla SOURCE.json: source fields from pdfcraft
  ec0a965 / krilla 0.8.2, sha256 recomputed for merged files.
- krilla PNG decode cap from main recorded as patches/11-png-decode-cap.patch
  with its ledger row and README section.

James ChapmanandClaude Code f20f364d55 hayro-jbig2: cap long-form referred-to segment count (#176)
* hayro-jbig2: cap long-form referred-to-segment count

A crafted JBIG2 segment header can claim a 29-bit referred-to-segment count;
Vec::with_capacity reserved ~2 GiB from that field before a single
referred-to number was read, and the resulting allocation failure aborts
the process in a way catch_unwind cannot contain (fatal on wasm32, where
memory is capped well below 2 GiB). A ~100 KB Flate-compressed PDF was
enough to reach it inside the 256 MiB stream budget.

Real files refer to a handful of segments, so the count is now capped at
u16::MAX; larger claims fail as InvalidReferredCount before any
retention-flag bytes are consumed. Regression test included.

Updates SOURCE.json's local hash for src/segment.rs and records the patch
in vendor/README.craft-reader.md, following the vendored tree's provenance
practice.

* hayro-jbig2: record git-blob sha256 for patched segment.rs

The previous entry hashed the Windows working-tree checkout (CRLF) of
src/segment.rs instead of the LF content git stores, so every other
manifest entry's convention (git-blob content hash) was broken by this
one file. Re-hash against `git show HEAD:vendor/hayro-jbig2/src/segment.rs`
as the vendored manifests' other 30 entries do.

aiongg b6f60f25b1 vendor: re-sync hayro reader trees from pdfcraft ec0a965
Bring vendor/hayro, hayro-interpret, hayro-syntax and hayro-jbig2 to
storytold/pdfcraft ec0a965074f376a5bf610435948e4e5184bf3299 (main,
2026-10-19), from 7437bde. The local patches (per-document decode
limits, incomplete-content diagnostics, Hayro 0.8 resource scopes,
nesting cap, iterative page tree, TJ fill order, transfer rounding,
safety repairs) are carried by a three-way merge without conflicts.

The re-sync includes transparency group /I and /K reading (pdfcraft
#2027), patches 28, 29 and 31-34, and the reader fixes listed in
vendor/README.craft-reader.md. SOURCE.json manifests, NOTICE and the
craft-pdf README name the new source revision.
