docs(changelog): record #1225 frontend restructure (changelog + credits) (#1226)

Retroactive changelog + credits for the already-merged feature-folder restructure (PR #1225). Adds a 1.50.0 Changed entry (internal restructure, no user-facing change; additional architecture credited to cucadmuh) and a contributions line under Psychotoxical. cucadmuh is intentionally not added to the settings credits list.

 * New **Square Corners** toggle under **Settings → Appearance → Visual Options → Display** overrides the active theme to render cards and cover art with square, non-rounded corners. Covers album, playlist, artist and song cards, detail-page cover art, the Now Playing / Radio and fullscreen views, the cover lightbox, the queue cover, and the mini player. Off by default; buttons, inputs and dialogs keep the theme's corners.

+
+* Reorganised the frontend into a feature-folder architecture with a CI-enforced layering guard, added unit + behavior-scenario + boot-smoke test coverage, and introduced a compile-time frontend/backend IPC contract via tauri-specta. Internal only — no change to how the app looks or behaves.
