cyfung1031andClaude Haiku 5.5 be94112c8e M11: strip redundant ASCII stream wrappers during optimization (#989)
* cos: decode only the first filter of a stream, strictly

Stream::decoded_first_filter_strict decodes the outer filter of a chain and leaves the rest of the chain encoded, within a caller bound. The optimizer uses it to remove an ASCII85 or ASCIIHex wrapper without inflating the inner data.

* optimize: strip redundant ASCII wrappers from filtered streams

A stream whose filter array starts with ASCII85Decode or ASCIIHexDecode loses that outer layer when the serialized replacement is smaller. The inner encoded bytes are kept exactly, and the decoded stream is unchanged. Streams with DecodeParms, image, object stream, or Crypt filters are left alone, as are streams whose wrapper fails strict decoding.

4dafbfc325 M11: Reduce file size and Optimize PDF drop images nothing draws, such as a deleted image (#894)
Deleting an image with Edit a PDF removes its Do operation, but the image stays in the
page's /Resources /XObject, so every full rewrite (Reduce file size, Optimize PDF)
carried its data along: a page left blank still weighed the whole picture.

Clean Up now drops image and form XObjects from a page's own resources when their name
is written in no stream the document still uses. Shared and inherited resources are left
alone, and if any stream can't be read the way a viewer would read it, nothing is removed:
viewers look names up through parent resources, so only a name written nowhere is safe to
drop. doc_optimize reports unused_xobjects.

4fd2c2b3a3 M11: Reduce file size shrinks office scans, and never saves a bigger copy (refs #490) (#849)
Office scanners write the default decode array (/Decode [0 1 0 1 0 1]) on their page
images. Reduce skipped every image with a decode array, so a scan stayed the same
size. The default array is now treated as absent; any other array still skips the
image.

Reduce also saved its copy even when it wasn't smaller, reported as "-N% smaller".
It now saves nothing and says the file is already as small as it can be made;
doc_reduce returns "written": false. Optimize PDF still saves (what it discards
may matter more than the size) but says "not smaller".

2a35a1a76f M11: Optimize PDF and Reduce File Size run in the background with a progress bar (#370)
* M11: Optimize PDF and Reduce File Size run in the background with a progress bar

Advanced optimization and Reduce File Size did all their work on the UI
thread, so on a large file the window stopped repainting until they were
done and looked as if it had crashed.

- pdfcraft-optimize: optimize_with_progress reports each image and the
  clean-up; returning false stops with OptimizeError::Cancelled.
- engine: Session::optimize_job captures a copy of the document and the
  choices; OptimizeJob::run reports each OptimizeStage (removing user data,
  images, cleaning up, merging, writing), stops on request with
  EditError::Cancelled and turns a panic into an error so a worker always
  reports back. optimized_bytes is the job run in place.
- ui: both commands run the job on a worker thread (inline in tests and on
  the web), like OCR and Export. A card at the bottom centre shows the
  stage ("Optimizing... image 14 of 40"), a bar that eases towards the
  fraction with a light sweeping across it, the percentage and Cancel;
  notices stack above it. A second run is refused while one is going. The
  control channel's state includes the progress.

The headless doc_optimize and doc_reduce tools stay synchronous. New
strings are translated for es, fr, ja, zh-hans, zh-hant.

* Clippy: as_chunks in the signature image background test (follow-up to #355)

#360 switched the image test to as_chunks; #355 added another chunks_exact(4)
in the background test, which clippy's chunks_exact_to_as_chunks rejects.

Brandon ThomasandClaude Opus 5.5 d3db99818f Rename PrintCraft to PdfCraft (#174)
The app, crates, binaries, bundle id, packaging, icons, screenshots and docs are now
PdfCraft / pdfcraft (repo storytold/pdfcraft). On first launch the desktop app moves the
PrintCraft settings and crash-recovery folders to the new name, and both apps read settings
saved under the old storage key, so upgrades keep recent files, preferences and unsaved work.
The signing test fixtures keep their PrintCraft subject names (they are binary).

3908a03aa6 Optimizer: Audit space usage counts images PrintCraft added as images (#3)
Content added with Edit ▸ Add content records its image in the content stream's dictionary
(/PCAdded /Image). The audit claimed a page's content streams before its resources and
followed that reference, so an added image's bytes were reported as Content Streams and
Images showed 0 % (a 1.9 MB picture read as 99.9 % content). Resources are now claimed
first, so whatever a content stream's dictionary points at keeps its own category.

Brandon ThomasandClaude Opus 5.5 9fcece8afb M11.1: PDF Optimizer: new optimize crate measures each image's effective resolution where pages draw it and resamples (bicubic) and recompresses (JPEG quality steps or ZIP) colour and grayscale images, soft masks with them, only when smaller; discards thumbnails, alternate images, tags and print settings; Flate for unencoded streams. Reduce File Size now downsamples like Acrobat (150 ppi above 225, JPEG medium); Optimize PDF dialog (Images, Discard Objects, Discard User Data, Clean Up) composes Remove Hidden Information; doc_optimize tool (84 tools)
