Spread params into better-sqlite3 Statement.run/get/all so positional ? placeholders bind correctly. better-sqlite3 accepts positional args, not an array, so binding crashed whenever a query had parameters. Matches the bun:sqlite and node:sqlite adapters.
## Features
- Add bun:sqlite adapter with automatic runtime detection (Bun/Node)
- Add bulk API key import (format: `name|sk-key`, one per line)
## Fixes
- Fix add API key for custom providers
