Prefer prepared statement param types over JS-inferred types (was: Inconsistent query result with integer conversion in prepared statement)

Hi,

I'm experiencing an inconsistent behavior using prepared statements with integers and **inferred type**.

**Node.js** v22.15.0
**@duckdb/node-api** 1.4.4-r.1

I was expecting that binding an int value to a prepared query would have it compared consistently with a bigint column, instead it works only when the value is previously upcast with `BigInt()`.

Reproducer: expected 2 rows, query returns 3

```javascript
import { DuckDBInstance } from '@duckdb/node-api';

// Connect to instance
const instance = await DuckDBInstance.create(':memory:', {
TimeZone: 'UTC',
});
const connection = await instance.connect();

await connection.run(`
CREATE TABLE test (
value BIGINT
);
`);

// Seed values
const valueFrom = 1739408400000;
await connection.run(`
INSERT INTO test VALUES
(${valueFrom - 1}),
(${valueFrom}),
(${valueFrom + 1});
`);

// Prepare query
const query = await connection.prepare(`
SELECT value
FROM test
WHERE value >= $valueFrom;
`);

query.bind({
valueFrom: valueFrom, // works with BigInt(valueFrom)
});

// Perform query
const result = await query.runAndReadAll();

// Check results, 2 rows expected
const records = result.getRowObjects();
console.log(records.length); // prints 3
```

If I prepare the same query at the database level, it behaves as expected

This works: expected 2 rows, query returns 2

```javascript
import { DuckDBInstance } from '@duckdb/node-api';

// Connect to instance
const instance = await DuckDBInstance.create(':memory:', {
TimeZone: 'UTC',
});
const connection = await instance.connect();

await connection.run(`
CREATE TABLE test (
value BIGINT
);
`);

// Seed values
const valueFrom = 1739408400000;
await connection.run(`
INSERT INTO test VALUES
(${valueFrom - 1}),
(${valueFrom}),
(${valueFrom + 1});
`);

// Prepare query
await connection.run(`
PREPARE read_values AS
SELECT value
FROM test
WHERE value >= $valueFrom
`);

// Perform query
const result = await connection.runAndReadAll(`
EXECUTE read_values(valueFrom := ${valueFrom});
`);

// Check results, 2 rows expected
const records = result.getRowObjects();
console.log(records.length); // prints 2
