Tanish MankuandClaude 0a09864833 F1, F2: adapt to main and re-pin the Arabic layout golden ...

Rebase onto 7163ba3 (396 commits on). Three adaptations, none of them
behavioural:

- `crates/fonts` renamed its `arabic` module to `shaping` and added
  Thai, so `Family::width`'s callers moved; the italic argument is
  re-applied to all six, including one new call site main added in
  `draw_laid_shaped`.
- `Metrics::text_of` now returns `Cow<str>`, so the F2 tests compare
  through `as_deref()`.
- `unicode_map` writes into a struct field now, so `/Differences`
  inserts go to `out.encoding`.

`SMALL_ITEM_FINGERPRINT` in added/arabic_tests.rs is re-pinned, and this
is the part worth reviewing. That golden is the appearance-stream pin
F1's acceptance criteria asked for, which landed from the Arabic work
after F1 was written; it caught the change correctly. The item's Latin
run is "Hi " in Helvetica 12pt. The old character-class guess called H
680, i 260 and space 260 (14.4pt); the published metrics are 722, 222
and 278 (14.664pt), verified against the table. The Arabic clusters that
follow start 0.264pt further right, which is the intended effect: the
glyphs now land where the font says they do. The Arabic path itself is
untouched.

Also dropped from the rebase: a re-added ATTRIBUTION entry for
vendor/hayro-interpret/assets/LAB.icc, which main deleted in favour of
CGATS001Compat-v2-micro.icc. Carrying it would have attributed a file
that no longer exists.
