v0.7.5 — the window earns its name

The "What's new" window earns its name: it now looks like release notes instead of a wall of plain text.

Changed

• The "What's new" window looks like the app talking, not a text dump. It gains a header with the app icon, a large title and the version with its release date; section names render as small colored labels (added green, fixed blue, changed amber); the changelog's bold lead sentences actually show bold in full text color while the prose around them steps back to secondary, and inline code gets a monospaced face — so the window scans like release notes instead of a wall of matter-of-fact text. The panel content moved to its own source file and is rendered to an image by a bare harness, which is how both light and dark appearances were reviewed before shipping — main.swift never links into any test.

The DMG is not notarized (no Developer ID yet): on first launch macOS will object — right-click → Open, or allow it in System Settings → Privacy & Security. The plugin channel and the in-app source build are unaffected.
