v0.7.1 — /silhouette

Added

• POST /silhouette — two-tone silhouette portrait. Subject filled with one solid color, background filled with another. Apple Music / Spotify avatar style. Use for stylized profile pictures, podcast cover art, anonymized portraits, branding placeholders.

Why a patch bump

No new model, no new dependency. Reuses the existing BiRefNet mask path then composites two flat colors. ~30 lines of glue around what was already loaded.

Endpoint count

22 endpoints in one image API (was 21).
