fix(manifest): deterministic element ID generation for Turbopack#4
Conversation
…ydration mismatches Next.js 16 with Turbopack runs server and client compilations in separate worker contexts, each with independent IDStabilizer singletons. Random IDs from nanoid caused every data-ds attribute to mismatch during hydration. Replace generateEntryId() (nanoid) with a deterministic derivation: hash(fileContentHash + positionKey) → base58 alphabet mapping. Two independent processes with identical inputs now produce identical IDs.
