feat(theme): optional RSS feed of params.links

Closes #8.

Opt-in via `params.rss = true` (off by default). When enabled:
- layouts/index.rss.xml renders an RSS 2.0 feed of [[params.links]]
  at /index.xml — one <item> per link, pubDate = build time
- head.html emits <link rel="alternate" type="application/rss+xml">
- Users must remove "RSS" from their disableKinds to let Hugo emit it

Channel populated from params.{name,tagline,bio} and site.BaseURL.
Item shape: <title> = link title, <link> = link URL,
<guid isPermaLink="false"> = bonsai-link-{url}, optional <description>.

XML declaration uses safeHTML+printf to defeat Hugo's default escape
(otherwise '<?xml ... ?>' becomes '&lt;?xml ... ?&gt;' and breaks parsers).

exampleSite enables rss=true to demo the feature; verified output
parses as valid XML via Python ElementTree.

- **Favicon polish** — opt-in `params.faviconSvg` and `params.appleTouchIcon` for SVG and iOS home-screen icons. Default behavior unchanged when unset.
- **Demo-only gallery CSS** — `/themes/` and `/variants/` pages load a separate `static/css/gallery.css`; `static/css/bonsai.css` no longer ships gallery selectors to user sites. Saves ~1.9 KB raw / ~200 B gzipped on every real site. New `head_extra` block in `baseof.html` enables per-page stylesheet additions.
- **10 new icons** — set grows from 35 to 45. Brand additions: `bandcamp`, `soundcloud`, `spotify`, `figma`, `dribbble`, `stackoverflow`, `matrix`. Utility additions: `bookopen`, `download`, `heart`. Vendored from Simple Icons v13 (CC0) and Lucide v0.460 (ISC) at the same versions; soft ceiling for v0-line is ~50.
- **Optional RSS feed** — opt-in `params.rss = true` renders an RSS 2.0 feed of `[[params.links]]` at `/index.xml` and emits `<link rel="alternate">` in `<head>`. Requires removing `RSS` from `disableKinds`. `pubDate` = build time. Off by default; existing sites unaffected.
### Changed
- **A11y** — sakura accent darkened `#d4456a → #c93f63` (4.04 → 4.49 vs bg) and koi accent darkened `#c8521e → #bd4c1c` (4.17 → 4.63 vs bg) to reach WCAG AA on the gallery accent chip. Brand intent preserved (cherry blossom pink / koi orange). README hex table synced.

## RSS feed (opt-in)
Off by default. To enable a feed of your `[[params.links]]` at `/index.xml`:
```toml
# remove "RSS" from disableKinds — Hugo emits it by default but the theme suggests disabling it
disableKinds = ["taxonomy", "term", "sitemap", "404"]
[params]
rss = true
```
The theme renders one `<item>` per link. `pubDate` is the build time (links lack intrinsic dates), so the feed updates whenever the site rebuilds — fine for a curated bio, less ideal for high-frequency feeds.
## i18n
Theme-rendered strings (nav landmark, theme-toggle labels, default footer) live in `i18n/{lang}.toml`. Bundles for `en` and `vi` ship with the theme.
