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.

+// Reading a community theme's actual shipped format.
+//
+// Omarchy's own 22 themes carry a `colors.toml` in the semantic shape `palette.ts` expects — three
+// background depths, four foreground weights, an accent, a selection, a muted. A community theme on
+// omarchythemes.com ships none of that: it's per-app config files in the classic 16-ANSI-slot style,
+// because that's what predates Omarchy 4's own format and what most single-theme repos still use.
+//
+// This file reads the two shapes that cover almost every repo: `alacritty.toml` (structured, typed,
+// preferred) and `ghostty.conf`/`ghostty-theme` (flat `key = value` lines, fallback). Either becomes an
+// `AnsiSource` — the 16 ANSI slots plus primary background/foreground — which `from-ansi.ts` turns into
+// the same `Palette` shape the official pipeline consumes, so every downstream guarantee (contrast
+// checking, the 84-token mapping) applies unchanged.
