Placard 1.0.0 — bake library names onto backdrops

Jellyfin 10.11 plugin: a scheduled task that labels each library card with the
library name over a representative backdrop (Noto Sans, centered, soft shadow),
matching Jellyfin's default cover style. Supports source rules (top-rated /
random / newest) and per-library pinned sources. Sets images via the internal
provider API so the home-screen view cache updates without a server restart.

+## [1.0.0] - 2026-07-19
+
+### Added
+- Scheduled task ("Generate Placard library cards") that bakes each library's
+  name onto a representative backdrop, matching Jellyfin's default cover style
+  (Noto Sans, centered, soft drop shadow over a darkening scrim).
+- Backdrop source rules: highest-rated / random / newest title in the library.
+- Per-library pinned sources (`Library Name=Item Title`) to override the rule.
+- Configuration page (enable, source rule, scrim opacity, label size, pins).
+- SkiaSharp-based renderer, incl. a procedural SMPTE color-bars generator for
+  views that have no media backdrop.
+
+### Notes
+- Sets images through the internal provider API, so the home-screen view cache
+  updates without a server restart.
+- Special views (Live TV / Playlists) are scaffolded (`IncludeSpecialViews`,
+  color-bars renderer) but not yet wired into the task. Planned for 1.1.
