sqlite3: `timeout` parameter doesn't accept int

[ever0de]

Current Problem:

struct ConnectArgs {
    timeout: f64,  // ← Doesn't accept int
    ...
}

Error Message:

TypeError: Expected type 'float' but 'int' found.

Test Proof:

# This fails
sqlite3.connect(":memory:", timeout=0)  # 0 is int

# Only this works
sqlite3.connect(":memory:", timeout=0.0)  # 0.0 is float
