Function init_database 

pub fn init_database(name: &str) -> Result<()>

Initializes a new SQLite database file.

This function creates a new database file at the specified path. It includes logic to:

• Append .db if not present.
• Check if the database already exists to prevent overwriting.
• Create parent directories if they don’t exist.
• Use a retry mechanism for creating the connection.
• Verify the integrity of the newly created database.

Arguments

• name - The name of the database file to create.

Returns

A Result which is Ok(()) on successful creation, or an Err with context if it fails.
