Fix crash in Glide Compose integration during fast scroll (#5739)

[karandhaodiyal28-hash]

Fixes #5739

During fast scrolling of a \GlideImage\ inside a \LazyColumn/\LazyRow, the app would crash with:

\
java.lang.IllegalStateException: This node does not have an owner.
at androidx.compose.ui.Modifier.Node.getCoroutineScope(Modifier.kt:188)
at com.bumptech.glide.integration.compose.GlideNode.launchRequest.invoke(GlideModifier.kt:405)
\\

Root cause: the existing \isAttached\ guard at the call site (in \onEndApplyChanges) checks the flag synchronously, but the \sideEffect\ that actually calls \coroutineScope\ is invoked later by the Compose runtime. A fast scroll can detach the \GlideNode\ between those two points, so the \coroutineScope\ property getter then throws.

Fix: re-check \isAttached\ inside the \sideEffect\ block, before touching \coroutineScope. If the node is no longer attached, skip the launch — the image is not on screen, so there is no request to issue.

Adds a regression test that mounts 20 \GlideImage\s in a \LazyRow\ and rapidly scrolls back and forth through all indices, then verifies that no exception is thrown and the surviving items still render correctly.

Hi! Quick note on the CI status for transparency — the two failing checks are pre-existing on the base branch and unrelated to the 2-file diff in this PR.

Failing checks

1. \zizmor-output\ (zizmor/unpinned-uses)

Failing on 7 occurrences across 3 workflow files that exist on the \move_logic_into_glide_node\ base:

• .github/workflows/build.yml\ (lines 12, 13, 17)
• .github/workflows/gradle-wrapper-validation.yml\ (lines 9, 10)
• .github/workflows/renovate-config-validation.yml\ (lines 8, 9)

None of these are touched by this PR (diff is +48/-0 across 2 files in \integration/compose/). The base branch's HEAD (\582077df4) has no check runs of its own, but the workflow files it carries are exactly the ones zizmor is flagging on this PR.

Happy to send a follow-up PR that pins the action references to SHAs, or you can address them separately — just let me know.

2. \import/copybara\ (status context)

Errored with "An error happened while migrating the change". Google-internal import infrastructure, not under this PR's control.

What's actually going well

• \cla/google\ ✅
• \check-changes\ ✅
• \zizmor-scan, \zizmor-config, \zizmor-upload\ ✅
• PR is \MERGEABLE\ per branch protection state
• The actual \Android CI\ (build.yml) hasn't started yet on this commit — would appreciate confirmation on whether it should trigger automatically

The actual change in this PR

Just two files in \integration/compose/:

• \GlideModifier.kt\ (+7 lines): re-check \isAttached\ inside the \sideEffect\ block in \launchRequest. Fixes the \IllegalStateException\ from the issue's stack trace.
• \GlideImageTest.kt\ (+41 lines): \glideImage_rapidLazyRowScroll_doesNotThrowDetachedScopeException\ regression test.

Let me know if you'd like the workflow pinning in a separate PR, or anything else. 🙏
