internal/pathrule/gen -dart renders the Unicode and best-fit tables as
const lists of a Dart library, as -ts does for datekeys-ts: the same data
and the same TablesDigest, with the formatter turned off for the file.
tables.go and the TypeScript module come out unchanged.

The key of words lowers each code point with the simple mapping of
UnicodeData.txt, field 13, of Unicode 18.0.0 (spec v0.11, 38.1), not
with unicode.ToLower, which carries Unicode 15.0.0: U+A7CB lowers to
U+0264 in Unicode 16.0 and later, and a key made in the page, whose
platform knows it, would not open in the CLI.
The generator writes the table for Go and for datekeys-ts, and the
canonical text gains its lines, so TablesDigest changes; paths.json and
path_fold.json record the new one.

A new flag, -ts, writes the same tables as tables.go as a TypeScript
module for the second implementation, which spec 29.5.1 requires to
use tables generated from the same pinned files and never the Unicode
functions of its platform: plain arrays of numbers, the sources and
TablesDigest, which its tests recompute from the arrays with the
canonical text of pathrule.Canonical.

internal/pathrule checks the paths and the texts of a format 3 head
(spec 29.5, 29.6) with its own tables, never with the Unicode functions
of the platform, whose version changes with each runtime.
- gen reads the 19 pinned data files (UnicodeData, DerivedCoreProperties,
CaseFolding and emoji-variation-sequences of Unicode 18.0.0, and the
15 WindowsBestFit tables), checks their SHA-256 and writes tables.go:
assigned code points, Default_Ignorable_Code_Point, full canonical
decompositions and combining classes, C and F folding, the bases of
the emoji variation sequences, and the non-ASCII code points each
code page maps to ASCII. The data files stay out of git, in .cache.
- NFD, Fold and the key of R7; CheckPath with R2 to R6c and R10,
CheckTree with R7 and then R9, and CheckComment and CheckAuthor with
the invisible-character rule. Errors name the rule and never echo the
creator's text, so that another implementation can match them.
- The canonical text of the tables has a SHA-256, TablesDigest, which
the tests recompute and a TypeScript implementation will share.
- Checked against golang.org/x/text (Unicode 15.0.0) outside this
module: NFD matches on every code point both know, and folding only
differs on the 86 Cherokee letters that CaseFolding.txt folds to upper
case, as these tables do.
- The spec pins the SHA-256 of the 19 files in 29.5.1.
