Pull request overview

Advances the deprecation lifecycle by escalating several deprecated Kotlin SDK APIs to DeprecationLevel.ERROR and removing old-schema tests/usages that would now fail compilation.

Changes:

• Raised deprecation levels for multiple legacy APIs (constructors/functions/aliases) from WARNING to ERROR.
• Removed old-schema test suites and integration tests that relied on now-error deprecated APIs.
• Added targeted suppressions and updated a few imports to use io.modelcontextprotocol.kotlin.sdk.types.*.
