Switch to pure-Go SQLite driver for cross-compilation

- Replace mattn/go-sqlite3 with modernc.org/sqlite (pure-Go, no CGO required)
- Update GoReleaser config to disable CGO for ARM64 builds
- Change driver name from 'sqlite3' to 'sqlite' in all sql.Open calls
- Enables successful cross-compilation for ARM64 without cross-compiler toolchain
- All tests passing with new driver
