Patch Changes

• #1686 `1e49880` Thanks @threepointone! - Batch and pack chat-persistence SQLite writes to reduce rows written and round-trips.
• agents: ResumableStream now packs each buffered group of stream chunks into a single SQLite row (a JSON array of chunk bodies) instead of writing one row per chunk. Single-chunk and large-chunk segments are stored unwrapped, and a per-segment byte cap keeps rows within the 2 MB SQLite row limit. This cuts chunk rows written / stored / scanned-on-replay by up to ~10×. Reads (replay, orphan reconstruction, getStreamChunks) transparently unpack both packed segments and legacy per-chunk rows, so existing stored data keeps working. Adds shared buildInClauseStrings and MAX_BOUND_PARAMS helpers exported from agents/chat.
• @cloudflare/ai-chat: message cleanup (stale-row pruning and maxPersistedMessages enforcement) previously issued one DELETE per row in a loop; it now deletes rows in batched DELETE ... WHERE id IN (...) queries (capped at 100 bound parameters per query).
• @cloudflare/think: deleteSubmissions() cleanup previously issued one DELETE per terminal submission (up to 500 per call); it now deletes rows in batched DELETE ... WHERE submission_id IN (...) queries.
• @cloudflare/ai-chat & @cloudflare/think: chat-recovery incident TTL sweep previously deleted each stale incident with a separate awaited storage.delete(key) (which also defeats Durable Object write-coalescing); it now deletes incidents in batched storage.delete(keys) calls (up to 128 keys per call).
