* XFA: choice lists, signature, password, image and barcode fields; PNG and GIF pictures
The xfa crate lays out the field kinds that were left blank or shown as
text fields:
- Choice lists become combo boxes (editable with textEntry) or list
boxes (open="always"; multi-select with open="multiSelect"), with the
shown items and the saved values of <items save="1"> as /Opt pairs,
/V, /I and /DV as saved values, several on separate lines in the
data. Field::saved_value maps shown text to saved values for the
layout and the script tree alike, so scripts read what is saved.
- Password fields are password text fields; signature fields are /Sig
fields the app can sign.
- Image fields show the picture the data (base64) or the template
holds; barcode fields show their value as text, with a warning that
no bars are drawn.
- PNG and GIF pictures (fields and draws) are decoded to Flate image
XObjects with a soft mask for transparency; JPEGs stay as they were.
Sizes come from the headers, so layout never decodes; decoding is
capped at 40 million pixels and failures are warnings, not errors.
Engine: multi-select list values from scripts and data are one per
line. README and parity notes updated (form.xfa-dynamic).
Hardened after an adversarial review pass: picture sizes refused from
the header past 20 million pixels or 65,535 a side, the GIF decoder
given limits (a frame far larger than its screen is refused before
allocation), template pictures read whole up to 32 MB, pictures
decoded once and remembered in the catalog by content hash so
re-layouts reuse them, data pictures that aren't images reported by
field; choice values matched against saved values first, several
values deduplicated and capped, /I ascending and unique, /DV through
the same mapping, <value> children read, the item cap reported; the
reopen path takes another viewer's choice values (several per line);
CMYK JPEGs inverted only with Adobe APP14.
* D5: README for cos and engine, and an honest cos status line
Thirteen crates have no README, although the session protocol tells every session to read the README of the crate it is touching. These are the two biggest: cos is where every hostile file lands first, and engine is the whole API surface a frontend gets.
Each states its layer and the rules that bind it, sketches the API against the real signatures, and ends with what is deliberately not done. The cos README spells out the clone-is-a-snapshot property and why both writers return bytes rather than taking a sink; the engine README spells out the four-step editing model that makes what you see what Save writes.
Also corrects the module doc on cos/src/lib.rs, which still said encryption and object-stream output for full saves were not done. Both shipped: security.rs handles R2-R6 with crypt filters and /EFF, and SaveOptions::object_streams defaults to true.

* Preserve alternate appearances and indirect push-button values
Keep rollover, down and custom appearance entries when normal appearances are regenerated, without modifying shared dictionaries. Resolve indirect button caption and layout values. Cover full and incremental saved output, and wait for raster readiness in the existing Linux scroll test.

* M13: common MCP tools through the confined automation path
Preserve task tools and compact mode, add complete hints and strict argument-key errors, and catch escaped tool panics.

* M13: session resources and version-aware MCP result hints
Keep per-document resources and legacy response shapes; add document/command resources and private cache hints for modern clients.

* pdfcraft-cli --help lists `mcp` only when the build has it
Follow-up to #540: a build without the `mcp` feature (`--no-default-features`) still listed
`pdfcraft-cli mcp` in its usage, and `pdfcraft-cli mcp` then said "unknown command".
USAGE is now put together with `concat!`, and its `mcp` lines come from a macro that is empty
without the feature. In such a build `pdfcraft-cli mcp` says the MCP server was left out instead
of calling it an unknown command.
- tests/help.rs: usage_lists_mcp_only_when_built_with_it (runs in both feature sets) and
mcp_without_the_feature_says_it_was_left_out (without the feature)

* engine README: the execution plan is local-only, so don't link a path that doesn't exist
* Merge land/450 into land/414; XFA pictures are found again by a SHA-256 on their XObject
The image cache was a /PCXfaImages map in the catalog, keyed by DefaultHasher
(not stable across Rust releases) and read back from the file. Each image
XObject now records the SHA-256 of its picture's bytes, and a re-layout finds
the XObjects on the pages it replaces by that hash; nothing goes in the catalog.

* Merge land/414 into land/451; keep main's MCP protocol versions, cap command_batch at 1000 steps
The 2026-07-28 revision and its resultType/ttlMs/cacheScope fields are dropped:
main doesn't advertise them and they couldn't be checked against the spec.
command_batch refuses more than 1000 steps. docs/mcp.md says that unknown
argument keys are now refused with -32602 (a behaviour change for clients that
sent extra keys).
