A descriptor class or key id is a u32 length and bytes, where length 0
means a 4-byte code follows. Photoshop stores `warp`, `list` and `time`
as length-4 strings and treats the code form as a different key, so the
warps of new smart objects and type layers and regenerated layer comp
lists were not recognised. In the corpus, `warp` appears 741 times as a
string and never as a code, `list` 5/0, `time` 7/0.
`Id::new` now makes these three names string ids, as keys and class ids.
Reading is byte-based and accepts both forms; a code read from a file is
written back as a code.
Tests: exact bytes for each name as class and key, both forms read,
fresh placed-layer warp (SoLd/PlLd) and layer comp list bytes.

View › Rulers (⌘R) now writes unitsAndRulers.showRulers, which is applied
at launch and whenever the preference changes, so new and opened documents
show the rulers as last set, as in Photoshop. The Preferences dialog doesn't
list it: the View menu sets it.
Guides are Vec<f64> (doc, New Guide/Move Guide, guide layouts, artboard and
canvas geometry, snapping, PSD resource 1032), so a guide placed in ruler
units or read from a PSD's 1/32 px positions keeps its exact place.
Scorecard UI-217-20 done (part of #217).

Comp positions were computed with unchecked i32 arithmetic on values from
files: import added a layer's origin to the cmls `Ofst` (and truncated wider
integers with `as i32`), export subtracted the origin from the stored
position, and applying a comp subtracted the current position. Extreme values
panicked with overflow checks on and wrapped otherwise.
Import now keeps offsets at i64 and drops a position whose sum does not fit,
with an import warning; export omits an `Ofst` that does not fit; applying a
comp skips a move that does not fit. Visibility of the same entries is kept.

guides_in numbered the document guide list horizontal-first, but
psd_export writes resource 1032 vertical-first, so an artboard with
guides of both orientations was associated with the wrong guides.
Number vertical-first to match the resource.

CI's `cargo fmt --all -- --check` has failed on every run because the
repo had no rustfmt config and was never formatted. Use the same settings
as EffectCraft/FilmCraft (max_width 160, use_small_heuristics Max), which
also keeps the churn small. Formatting only; no code changes.
