CoODL - Release history

Archived release notes for CoODL releases prior to the current ROADMAP.md scope. Split across per-era files to stay under the 200-line hard rule:

• elease-history/v1.0-v1.8.md \u2014 Foundation + UI maturity eras (v1.0 through v1.8.3). Covers the initial launcher, slot naming, tray integration, resource monitoring, login persistence, startup toggle, configurable refresh interval, and the UserControl split.
• elease-history/v1.9.md \u2014 Thumbnail-and-card series (v1.9.0, v1.9.1, v1.9.2). Covers thumbnail capture infrastructure, the grid-card layout migration, and click-to-enlarge preview.

The current ROADMAP.md covers only v1.10.0 onwards.
