Koin 4.2.1-RC1

Bug Fixes

• Fix ABI break on runOnKoinStarted (#2391) — The 4.2.0 refactor to move waitAllStartJobs to common code changed the JVM symbol for runOnKoinStarted from KoinWaitExtKt to KoinWaitExt_jvmKt, causing NoSuchMethodError at runtime for libraries compiled against 4.1.x. Fixed by adding @file:JvmName("KoinWaitExtKt") and @file:JvmMultifileClass to restore the original symbol.

• Improved scope resolution error messages (#2379) — NoDefinitionFoundException now displays the full scope chain that was searched and indicates which scope qualifier is missing a definition, making scope resolution issues much easier to diagnose.

CI / Tooling

• Added apiCheck to CI — The binary-compatibility-validator plugin was already configured but not running on PRs. apiCheck is now part of the CI build workflow, preventing accidental ABI breaks in future releases.
• Updated .api dump files for all modules to reflect the current public API surface.

Still in progress for 4.2.1 final

• PR #2389 — @Volatile on Scope._closed for concurrency fix
• PR #2358 — Fix ClassCastException reading environment properties (#2348)
• Documentation updates: #2339, #2336, #2328, #2218
