fix(compose): add isImportantForBounds() to SentryTagModifierNode for compose-ui 1.11+

[tsushanth]

Fixes #5662

Problem

compose-ui 1.11 added SemanticsModifierNode.isImportantForBounds() as an abstract method. SentryTagModifierNode was compiled against compose-ui 1.6.x, where the method does not exist, so its class bytecode has no implementation. When an accessibility client (TalkBack, UiAutomator2, adb shell uiautomator dump) traverses the Compose semantics tree at runtime with compose-ui 1.11+, the JVM cannot find the method and throws:

AbstractMethodError: abstract method "boolean androidx.compose.ui.node.SemanticsModifierNode.isImportantForBounds()"
    at SentryTagModifierNode (SentryModifier.kt)

Fix

Add fun isImportantForBounds(): Boolean = false to SentryTagModifierNode.

The override keyword is intentionally omitted because the method is absent from the compose-ui 1.6.x compile-time dependency — using override would fail to compile. The JVM satisfies the abstract-method contract at runtime via bytecode signature matching, regardless of whether the Kotlin compiler knew about the override at compile time.

SentryTagModifierNode stores only a semantic tag with no layout or visual effect, so false is the correct return value (it does not affect touch-bounds computation).

Testing

Verified no public API changes (./gradlew sentry-compose:apiCheck passes — SentryTagModifierNode is private, so no .api file update required). The fix applies cleanly to the existing compose-ui 1.6.x compile target without version bumps.

Thank you for your work on this @tsushanth 🙇
The fix LGTM 🚀

I reproduced the issue on a Pixel 8 Pro (Android 16) using sentry-samples-android. Repro patch (apply on main):
