New standalone L0 crate pdfcraft-prc: the PRC container walk (file
header, file-structure descriptions, per-section zlib inflation under a
512 MiB ceiling), the bit-level primitives of the compressed sections,
and the schema interpreter a newer producer uses to describe fields it
added (step and nesting ceilings).
The Double prefix-code table is not in this commit: Double reads
return UnknownDoubleCode, and the tests that need the table are
ignored with that reason.

The centred 4 pt strip still covered the right 3 pt of the page's
scrollbar beside a right-docked pane. Register the host's resize edge
again from the border rightwards, on the host's own layer, and leave an
inert edge inert. The test now hovers and drags both scrollbars beside a
right-docked Tools pane (CodeRabbit) and checks the width is unchanged.
`ImageBudget::decode` is now the one public way to decode an image's
CCITT fax or JBIG2 data: `Document::decoded_image` and
`decoded_image_within`, which decoded with no limit on the work, are
test-only in pdfcraft-cos, and pdfcraft-filters exports only
`decode_ccitt_within` and `decode_jbig2_within`, which spend from a
caller's allowance (`decode_jbig2` is gone, `decode_ccitt` private).
So an operation over many images can't decode them without sharing an
allowance; the compiler holds new callers to it. Doctests that must not
compile check both crates; with the old entry points public they fail.
Tests outside the crates decode through an unlimited ImageBudget.
Streams in general (`Stream::decoded`) are left for a follow-up.
It reserves room for a translated "Mixed", and in Czech or French that pushed the alignment
button up to 54 pt past the Tools pane. The field is now no wider than SIZE_FIELD, and a longer
translation scrolls in it. The language test checks the size row too.
Conflict with main's rail docking, resolved by keeping both: the rail follows the side chosen
for it (main) at 49 pt with 1 pt padding, and main's dock button stays above the page display
button, while zoom out and in stay side by side under the zoom field.
Conflict with main's hotbar, resolved by keeping both: the bar keeps main's offset past a hotbar
docked on the left or top, and centres in the margin that starts after it.
Conflicts with main's font menu, size field and accessible names, resolved by keeping both:
the font list keeps main's searchable installed-fonts menu inside its outline; the line spacing
list and number fields keep their names. The size field now reserves room for "Mixed", so
MIN_ROW counts it (62 pt, measured for English), and the spacing columns take their width from
the font list so a longer translation of "Mixed" can't widen them.

* A rebuilt xref finds an object whose header names another generation (#5580)
`poppler-85140-0.pdf` is 340 bytes with no cross-reference table, and the
header of its one page reads `3 18446744073709551616 obj` while the page tree
points at `3 0 R`. Before #427 the digits wrapped and 2^64 wrapped to exactly
0, so the header read as `3 0 obj` and the file opened by accident. Once an
overflowing integer became a real, the object was unreachable and the file
stopped opening at all, which `cargo xtask check` reports as a regression.
The generation is not really the point. `3 99999 obj` with the same page tree
is refused in exactly the same way on main -- the control for the new test
fails on that row first, with "page 1 does not exist" -- so this is a
mismatched generation in a rebuilt table, not an integer overflow. A table
rebuilt by scanning the file has no revision history to tell two generations of
an object apart, and a file that needs rebuilding references everything as
`N 0 R` whatever its headers say.
So, in the reconstruction path only:
- a generation number that cannot be read is taken as 0, the value such a
file's references use (`read_object_header`). A generation is at most
65,535 (ISO 32000-2 §7.5.4), so there is nothing to lose by it;
- every scanned object is also filed under generation 0, with `or_insert` so
a real `N 0 obj` is never displaced by the alias;
- the object is read back behind the same lenient header, since reading it
parses the header again and the strict identifier check rejected it
(`read_repaired_body`, gated on `repaired`).
Reading numbers anywhere else is unchanged, and a table read from the file's
own xref keeps the exact identifier match. The scan already files objects found
in object streams under generation 0, and cos's table parser already takes an
unreadable generation as 0, so this follows what the code does elsewhere.
The test covers generations 0, 99999 and 2^64 with no table and no `startxref`,
and asserts the page is found at its own size. Its fixture is built in the test
rather than taken from the corpus, so it holds without the pinned checkout.
* The generation-0 stand-in is one key, not a second object
Two consequences of filing a scanned object under generation 0 as well,
both from review.
`XRef::objects` walks the table's keys, so an object with a stand-in came out
once per key: a document whose page tree cannot be read is recovered by looking
for objects that are pages, and it reported the page twice. Enumeration now
yields one object per location, after the sort it already does. Both keys stay
for lookups; only this walk is deduplicated.
And `or_insert` never replaces, so a later `3 1 obj` moved the exact `3 1` key
to the later body while the `3 0` stand-in stayed on the earlier one -- `3 0 R`
and `3 1 R` would then read different objects. The scan now tracks which
generation-0 keys are stand-ins: a real `N 0 obj` takes the key and keeps it,
and a later header for the same number replaces a stand-in.
The tests check both through what comes out: page 2 must not exist for a
single-page file recovered without a page tree, and with two `3 1 obj` headers
the page comes back at the later body's 300x150 rather than the earlier
200x100.
* M2: the repair scan keeps its place on a non-header, and an object stream's first member is enumerated (#5580)
- read_object_header's lenient path works on a clone, so `42 3 0 obj` no longer costs the
header after the stray number (CodeRabbit, minor).
- XRef::objects deduplicates by location and object number: an object stream and its first
member share (offset, 0) and are two objects (CodeRabbit, minor).
- vendor/README.md: hayro-syntax patch (34) and its tests.
Both new tests fail with their fix reverted.

* fix(ui): don't check recent files on the UI thread at startup (#5682)
Restoring settings dropped recent files whose files no longer exist by
asking the file system about each one on the UI thread, before the first
frame. On a network mount that has stopped answering (davfs2 in the
report) that call blocks in the kernel, so the window never appears.
Settings now keep every recent entry when they load. Once the window is
up, a worker checks the restored paths and each frame drops the ones it
has found gone. An entry it hasn't reached, or can't tell about (the
mount answers with an error), stays listed. A worker stuck on a dead
mount stays stuck, but nothing waits for it. This follows the pinned
folders' worker.
Fixes#5682

* Recent files: a file opened while the check is pending stays listed
The worker's answer that a restored path is gone is out of date once the
user opens that path; keep the new entry (CodeRabbit on #5692).

An image that shared a redacted image's /JBIG2Globals is now stored
again as the smallest of Flate, Group 4 or JBIG2 coded alone (smallest),
like a cleared copy, rather than always Flate, so the other pages of a
scan don't balloon either. The shared-globals test's second page is a
ragged scan and checks it is no longer Flate and is smaller.
A JBIG2 image's /JBIG2Globals hold the symbol dictionary of every image that
shares them (jbig2enc -s and most scanners give one to all of a scan's pages),
so the bitmaps of marks drawn only under a redaction stayed in the file while
another page's image used them. Every image using the globals of a removed or
replaced image (or of one in a removed or replaced form) is now decoded and
stored again in place as Flate without them; a full save then drops them. One
that can't be decoded for certain refuses the redaction
(RedactError::SharedJbig2Globals). Report::images_restored counts them.
