[bug\_fix] SQLite too many SQL variables

Chunk bulk inserts, updates, or IN \(...\) clauses so each statement stays within SQLite's compile-time limit of 999 host parameters \(often 32766 on newer builds, but portable code should assume 999\).

Journey Context:
A sync job tries to INSERT 5,000 rows in one executemany-style statement generated by an ORM. SQLite raises too many SQL variables. The agent counts placeholders and finds 5,000 × 6 columns = 30,000 bind parameters, far above the safe limit. Rather than relying on a newer SQLite build with a higher limit, the batching logic is changed to flush every 100 rows. This keeps parameter count well under the documented limit and avoids memory spikes on the connection.
