pastilhasandClaude Sonnet 5 861fc4a58b add colors.toml and 0x-hex support, rescuing 44 more community themes
Poked at the 62 "no parseable source" skips from the first pass and found two things
the pipeline didn't handle: several community repos genuinely ship colors.toml too — some
in Omarchy 4's own semantic schema (best case, no derivation needed at all, same quality
as the official 22), others reusing the filename for an unrelated flat color0..color15
scheme — and a handful of alacritty.toml files use 0xrrggbb instead of #rrggbb.

palette.ts's loadPalette is now a thin wrapper over two exported pieces (parseTomlText,
paletteFromRecord) so the community pipeline can attempt the real schema first without
duplicating the reader; falls through to the color16 or ANSI-derived paths otherwise.
generate-themes.ts --check still reports 0 changes for the official set — the refactor
is behavior-preserving there, the lowercase-hex normalization it picked up along the way
touched 7 official theme files cosmetically (their source colors.toml has uppercase hex),
regenerated for real rather than left inconsistent with their own source.

147 -> 191 community themes ported. Of the original 62 unparseable repos, most turned out
to be simply gone (404 on GitHub — repos deleted or renamed since the site listed them);
the rest needed one of the two format additions above. 20 themes remain stuck: 16 dead
repos, 2 with no repo link at all, and the same handful of genuinely low-contrast source
palettes (mostly Solarized variants) where fixing contrast would mean changing the
author's actual colours rather than porting them.
