Adds the Character panel menu's Digits option (with the Middle Eastern /
Indic options, beside Paragraph Direction in the Paragraph panel) as a
character attribute: CharStyle::digits, saved only when set, with
text.setFormat {digits} and text.setRangeStyle {id, start, end, digits}
("default" | "arabic" | "hindi" | "farsi"; a bad value is an error).
Shaping draws every digit of the Western, Arabic-Indic (U+0660–U+0669)
and Eastern Arabic-Indic (U+06F0–U+06F9) sets in the chosen system,
whatever was typed, before font fallback, so a font without the
Arabic-Indic digits gets a fallback for them. The text, its clusters,
the caret, selection and search stay as typed, as with All Caps; SVG
export writes the digits as drawn.
Catalog rows for Digits, Arabic, Hindi and Farsi in the ten translated
languages. Docs: docs/mcp.md (Digits), type-parity.md (digit types
done; Character Direction, kashidas, composers and the split caret
still missing), target-app-parity.md and gaps.md.
Behaviour from the public documentation (a character-level option with
the values Arabic, Hindi and Farsi in the Character panel menu):

Tests: doc (the mapping and serialization), text (glyphs of "page 3" in
Hindi/Farsi equal the typed Arabic-Indic digits' on the typed clusters;
skips without a font covering the three sets), engine (setFormat,
setRangeStyle, undo, error), svg (digits written as drawn), ui-egui
(the menu shows with the Indic options).

Ctrl/Alt+arrows and double-click treated a run of Thai (Lao, Khmer,
Myanmar) without spaces as one word, and stopped at a word's tone and
vowel marks, which didn't count as part of a word. They now stop at the
word boundaries the line segmenter finds in those scripts (shared with
line breaking, so no more data ships), and combining marks count as
part of a word, also for combining accents in other scripts.

The font menu's script filter offered Japanese and Latin only, so Thai
fonts had to be found by name among every installed family. It now has
Thai too: the families whose character map has Thai. Latin lists the
families with neither Japanese nor Thai.

These scripts don't separate words with spaces, and lines only broke at
spaces, hyphens and CJK characters, so a Thai paragraph in area type ran
on to the next space (or was cut wherever it overflowed). Each
paragraph's glyphs now carry the word ends ICU4X's line segmenter finds
in text of those scripts (its dictionaries on the desktop, its far
smaller LSTM models on the web), and a line may break after them as
after a space. Other text keeps its own breaks, and clusters (a
consonant with its vowel and tone marks) still never split.

The Type tool's Left and Right arrows and Delete moved one code point at
a time, so the caret could stop between a Thai consonant and its vowel
or tone marks (or inside an accented letter or emoji sequence), where
typing or deleting splits the cluster. They now step over extended
grapheme clusters. Backspace still takes back one character at a time,
as Thai typists expect for a mistyped tone mark.

Thai typed in a font without Thai glyphs (Source Sans 3, a Latin font)
took the first loaded face that had them, or the first installed file
that did, in path order: on one Windows machine a display face (Kanit)
rather than Leelawadee UI. Characters of Thai, Lao, Khmer and Myanmar
now try fonts made for their script first, installed ones loaded on
demand (Leelawadee UI, Tahoma, Thonburi, Sukhumvit Set, Noto Sans Thai,
the TLWG fonts for Thai), then the fallback as before. Latin beside
them keeps the font chosen.

The second half of #966. With Proportional Metrics on, a vertical segment is
also shaped top to bottom, with and without `vpal`: the difference gives
each glyph's change of advance down the column and its x and y placement.
An upright glyph (not tate-chu-yoko) in a font with vertical metrics takes
them on top of its cell, so it moves with its shorter cell; a font without
vertical metrics keeps `upright_cell`'s cell, and with the switch off
nothing is shaped twice and the column is as before.
As in horizontal type, Line-end Punctuation Half Width takes nothing more
off the punctuation `vpal` re-spaced and trims the punctuation it leaves
full height as before. Docs: mcp.md, and Proportional Metrics leaves the
missing lists in gaps.md, type-parity.md and target-app-parity.md.

After scaling 12 pt type 2x, the Character panel still showed 12 pt and
typing 10 pt gave 20 pt type. Character controls and text commands now
work in document points: the size, leading and baseline shift shown and
set are the stored ones times the text's scale along its em height, and
horizontal scale includes the ratio of the transformed em axes. Rotation,
reflection and shear stay in the transform, so text remains editable.
Groups' text counts, keyboard increments use the same units, Shrink
Text to Fit works in document tenths, and a collapsed transform rejects
dimensional edits without touching the document.
text.getRange takes effective: true for the document-space values.
