/**
 * Compaction Restoration — Re-inject memories after session compact.
 *
 * Pattern sourced from opencode-mem (tickernelz/opencode-mem).
 * After a session compaction event, relevant vector memories are
 * re-injected into the session via session.prompt with synthetic:true
 * parts so future messages benefit from persisted knowledge.
 *
 * 0-risk principle (from MrGray17/opentoken):
 * - Every step is wrapped in try-catch with silent fallback
 * - Fire-and-forget: never blocks the compaction flow
 * - If any step fails, skip silently with a console.warn log
