port 147 community Omarchy themes from omarchythemes.com

The official 22 themes come from basecamp/omarchy's own colors.toml, contrast-checked
by generate-themes.ts. A community theme has no such file — it ships per-app configs
(alacritty.toml, ghostty.conf) in the older 16-ANSI-slot style, so this adds a sibling
pipeline: from-ansi.ts derives the same 24-key Palette shape by role (accent, three
background depths, three foreground weights) from those 16 slots, then runs through the
same mapPalette + contrast checks the official themes use. Nothing about the official
generator changed — verified generate-themes.ts --check still reports 0 changes.

port-community-themes.ts discovers each theme's GitHub repo from its omarchythemes.com
page, fetches alacritty.toml (preferred) or ghostty.conf, and is idempotent via
community-manifest.json so a re-run only fetches what's missing. Community themes get
their own registry/index.css marker block, separate from the official GENERATED THEMES
block, so the two pipelines can never clobber each other.

121 of 212 attempted made it through cleanly; a second pass tightening accent selection
and nudging --input recovered 20 more borderline cases (147 total). The rest failed for
real reasons: 62 repos had no parseable colour source, 7 had an accent colour whose own
luminance can't clear 4.5:1 against either black or white text, a handful were narrowly
under threshold even after the rescue pass, and 2 pages had no repo link at all. Every
generated file's header states its source repo and whether it's a light or dark theme.

+  Artzen — ported from a community Omarchy theme, not from basecamp/omarchy's own set.
+
+  Dark theme (dark), by luminance of its own
+  background — the source repo carries no mode flag of its own to read.
+
+  Source: https://github.com/tahfizhabib/omarchy-artzen-theme (alacritty.toml), read by scripts/port-community-themes.ts. Values
+  went through deriveOmarchyPalette (scripts/themes/from-ansi.ts) because a single-theme repo ships
+  per-app configs, not Omarchy 4's own colors.toml shape — some tokens here are reconstructed, not
+  authored. Every text/surface pair is contrast-checked the same way the official themes are.
+
+  DO NOT EDIT BY HAND. Re-run the script to refresh from the source repo.
