What changed

• Fix: crash on edge-to-edge Compose activities. DevDeck.install added its overlay ComposeView in onActivityStarted, before the window was attached. On recent Android an edge-to-edge window can measure it before attaching it, which crashes with "Cannot locate windowRecomposer; … is not attached to a window" (Android Studio's new-project template calls enableEdgeToEdge(), so many apps would hit this; 1.0.0 is affected). The overlay is now added once the window is attached, posted so it isn't added mid attach pass, and never to a finishing or destroyed activity.
• Sample: endless feed screen. Open endless feed (try a long screenshot) on the main screen opens a Compose list that loads 20 more items whenever you reach the bottom, with numbered, coloured items so seams or repeats in a long screenshot are easy to spot. It's attached through includeActivity, which is how the crash above was found.

How it was tested

• ./gradlew ktlintFormat ktlintCheck lintDebug lintRelease testDebugUnitTest assembleDebug assembleRelease publishToMavenLocal apiCheck :sample:assembleQa passes.
• Pixel 10 Pro emulator (API 37): the feed crashed with enableEdgeToEdge() before/after super.onCreate() and opens fine with the fix; the main (hosted) and View-based screens still get the drawer; no crashes in the crash buffer.
• Long screenshot on the feed: from item 7 with one page loaded it captures to the end of loaded content plus the spinner (1280×4040) and scrolls back; with ~26 pages loaded, from item 173 it stops at the pixel budget (1280×12114, items 173–221 in order, no repeats); no crash.

Checklist
