Pull request overview

This PR bumps the project version to 3.0.5 and refactors SurfPaperPacketApi’s companion object to follow the common “delegated companion singleton” pattern used across the Paper APIs.

Changes:

• Bump Gradle project version from 3.0.4 → 3.0.5.
• Refactor SurfPaperPacketApi companion object to delegate SurfPaperPacketApi to the service-resolved api.

File	Description
surf-api-paper/surf-api-paper/src/main/kotlin/dev/slne/surf/api/paper/packet/SurfPaperPacketApi.kt	Refactors companion object to companion object : SurfPaperPacketApi by api, keeping INSTANCE as the service entrypoint.
gradle.properties	Increments project version to 3.0.5.

[Copilot]

Removing @JvmStatic from the INSTANCE property changes the Java-facing API: callers that previously used SurfPaperPacketApi.getINSTANCE() (and binaries compiled against it) will break and now must use SurfPaperPacketApi.Companion.getINSTANCE(). If Java/source+binary compatibility is intended, keep @JvmStatic on INSTANCE (even with the delegated companion), or explicitly treat this as a breaking API change and version accordingly (and update ABI dump).

Suggested change

	companion object : SurfPaperPacketApi by api {
	companion object : SurfPaperPacketApi by api {
	@JvmStatic

[Copilot]

This is a patch-version bump, but the companion-object refactor in SurfPaperPacketApi can be a breaking change for Java callers/binary compatibility (loss of getINSTANCE() static accessor without @JvmStatic). Either preserve the previous Java API shape or consider a version bump consistent with a breaking change.
