CSV import: preview with inferred types

postgres-studiofeat/csv-preview 2 agents in this conversation

Add a preview step to the CSV import: before importing, show the first 20 rows with the type inferred for each column, and let me override a column's type.

Added a Preview step between choosing the file and importing. Rust samples the first 20 rows and infers a type per column; the dialog shows them in a grid where each header has a type menu. Import uses the chosen types.

Dedupe handoffs on reconnect

chupacabra-brainfix/handoff-dedupe

Handoffs are created twice when the MCP bridge reconnects. Find the cause and fix it.

Codexgpt-5-codexwaiting for you

The bridge retries handoff_begin without an idempotency key, so a reconnect inserts a second row. I'll add a key derived from the session and a unique index.
