feat(gui): global recording indicator in the sidebar — 0.18.0

While a capture runs, the sidebar shows a red "● Recording" badge on every page
with the game and live sample count (+ GPU-lost flag). A 1.5s poll of the
recorder status reflects captures started any way — manual record, a guided
diagnostic, or the Steam launch wrapper.

+### Added
+- **Global recording indicator.** While a capture is running, the sidebar shows a red
+  **● Recording** badge on every page — with the **game** being captured and the live sample
+  count (and a GPU-lost flag if seen). It polls the recorder, so it reflects captures started
+  any way: manual `record`, a guided diagnostic, or the Steam launch wrapper.

 ## [0.17.0] - 2026-05-22
 ### Added
 - **Inventory page is back in the GUI** (it was removed in 0.7.2 in favor of the CLI). Sidebar
