  1. Add diffHunkHeaders and diffLineNumberStyle modifiers 

    The library renders a side-by-side `old | new` gutter and an
`@@ -a,b +c,d @@` separator above every hunk. Both are right for
desktop unified-diff review and wrong for narrow viewports — on a
phone every context line shows the same number twice (e.g. `19 19`,
`20 20`) which reads as noise, and the hunk header eats screen space
without adding signal beyond what the surrounding chrome (file name,
stats badge) already conveys.

This adds two opt-in knobs that leave today's behaviour unchanged:

- `DiffConfiguration.LineNumberStyle = .hidden | .single | .dual`,
  default `.dual`. `.single` shows one column with the new line
  number for added/context and the old line number for removed —
  matching how `git diff --color` and most terminal renderers
  present a compact gutter.
- `.diffLineNumberStyle(_:)` view modifier sets it explicitly. The
  legacy `.diffLineNumbers(_:Bool)` modifier and the legacy
  `showLineNumbers: Bool` init parameter still work: `true` → `.dual`,
  `false` → `.hidden`.
- `showHunkHeaders: Bool`, default `true`, exposed via
  `.diffHunkHeaders(_:)`. Mirrors the existing
  `.diffFileHeaders(_:)` modifier.
- New `.mobile` preset bundles `.single` + hidden hunk headers +
  compact font/spacing for a sensible mobile default.

The existing modifiers (`.diffTheme`, `.diffFont`, `.diffLineSpacing`,
`.diffWordWrap`) were each manually re-instantiating
`DiffConfiguration` with the old field set — that would have silently
reset the new fields whenever chained after `.diffLineNumberStyle` /
`.diffHunkHeaders`. Switched them to the existing `.with*` builders
so every field flows through unchanged.

10 new tests cover field inference (legacy → new), the new
modifiers, the `.mobile` preset, and that chaining other modifiers
preserves the new fields. 21/21 passing total (was 11).
