/**
 * `@nestia/sdk` ttsc plugin descriptor.
 *
 * Points ttsc at this package's own Go source (`native/sdk`, package `sdk`).
 * Because that package is not `package main`, ttsc classifies it as a linked
 * transform and statically links it into the `@nestia/core` host binary as a
 * contributor — but only for projects that actually depend on `@nestia/sdk`. A
 * project depending on `@nestia/core` alone never links, compiles, or ships any
 * of this SDK transform code.
