// at `session_before_compact` and gated by
// `contextMode.llmSummarization && byteLength(snapshot) > contextMode.llmThreshold`.
//
// Registering here (rather than at the call site) keeps registration as a
// module side-effect, mirroring the pattern in `src/quality/ai-setup.ts`,
// `src/commands/plan.ts`, etc.
