docs(examples): gallery entries for inline chips, SVG, emoji, in-PDF navigation (#256)

Four v1.9.0 features visible in a rendered document had no gallery presence.
Add a row + detailed showcase section + a committed preview render for each,
with the API names read off the runnable *Example classes:

- Inline highlight chips (RichText.code / chip / highlight) — Core DSL.
- Inline SVG icons (RichText.svgIcon) — Core DSL.
- Colour emoji by shortcode (RichText.emoji) — Core DSL.
- In-PDF navigation (anchor / linkTo / inlineLinkTo / shapeLinkTo) — Advanced SPI.

The emoji preview uses the 44 KB shortcode showcase; the full emoji-gallery
render is 3.9 MB, too large for a committed README asset.

+### Inline highlight chips
+
+`RichText.code(text)` / `chip(text, fg, bg)` / `highlight(text, style, bg,
+radius, padding)` (`@since 1.9.0`) draw text on a rounded, padded background
+fill on the baseline — the GitHub inline `code` look and inline status badges.
+`code` ships engine defaults (monospace + a light chip), `chip` colours a
+badge, and `highlight` is the full primitive. A multi-word highlight wraps
+across lines, painting one continuous rounded fill per visual fragment. On
+`ParagraphBuilder` the calls are `inlineCode` / `inlineChip` / `inlineHighlight`.
+
+```java
+.addRich(rich -> rich
+        .plain("Run ").code("./mvnw verify").plain(" — status ")
+        .chip(" Paid ", paidFg, paidBg)
+        .highlight("rounded", style, fill, 8.0, DocumentInsets.symmetric(2, 8)))

+
+### Inline SVG icons
+
+`RichText.svgIcon(icon, size)` / `ParagraphBuilder.inlineSvgIcon(...)`
+(`@since 1.9.0`) place a parsed `SvgIcon` on the text baseline, so multi-colour
+vector glyphs flow inside a line of text — crisp at any zoom, carrying their own
+colours, with no dependence on the active font's glyph coverage. `size` is the
+glyph height in points; width follows the icon's aspect ratio. This is the
+engine path behind vector colour emoji.
+
+```java
+.addRich(rich -> rich
+        .svgIcon(check, 10).plain(" Deploy succeeded   ")
+        .svgIcon(warn, 10).plain(" Disk almost full"))

+
+### Colour emoji
+
+`RichText.emoji(":star:", size)` / `ParagraphBuilder.inlineEmoji(...)`
+(`@since 1.9.0`) resolve a GitHub-style shortcode to an inline vector colour
+glyph on the baseline — crisp at any zoom, no emoji font required. Glyphs come
+from the `graph-compose-emoji` companion artifact on the classpath. Resolution
+is lenient: an unknown shortcode falls back to its literal text, exactly the way
+GitHub renders an unrecognised `:code:`.
+
+```java
+.addRich(rich -> rich
+        .plain("Ship it ").emoji(":rocket:", 11).plain(" ")
+        .emoji(":white_check_mark:", 11).plain(" ").emoji(":tada:", 11))
