731c3f037a Merge 'Improve Python bindings' from Diego Reis 
Yet another PR to close #494.
While testing the code provided in the issue I noticed that it wasn't
closing the connection as it should, leading to lifetime issues like:
`Connection is unsendable, but is being dropped on another thread`. The
following code works fine:
```python
import limbo

def main():
    con = limbo.connect("test.db")
    cur = con.cursor()

    try:
        cur.execute("""
            CREATE TABLE IF NOT EXISTS users (
                id INTEGER PRIMARY KEY AUTOINCREMENT,
                username TEXT NOT NULL,
                email TEXT NOT NULL,
                role TEXT NOT NULL,
                created_at DATETIME NOT NULL DEFAULT (datetime('now'))
            )
        """)

        # Insert some sample data
        sample_users = [
            ("alice", "alice@example.com", "admin"),
            ("bob", "bob@example.com", "user"),
            ("charlie", "charlie@example.com", "moderator"),
            ("diana", "diana@example.com", "user")
        ]

        for username, email, role in sample_users:
            cur.execute("""
                INSERT INTO users (username, email, role)
                VALUES (?, ?, ?)
            """, (username, email, role))

        con.commit()

        # Query the table
        res = cur.execute("SELECT * FROM users")
        record = res.fetchone()
        print(record)

    finally:
        # Ensure connection is closed on the same thread <----
        con.close()
        pass

main()
```

To address these issues, this PR:
- Adds support for `with statement` a common resource management pattern
in Python;
- Close connection if it is dropped

Closes #1164

Start of syntax highlighting and hinting. Still need to figure out how
to sublime-syntax works to produce good highlights.
Edit:
Personally, I believe there are more interesting syntax highlighting
possibilities with `reedline` crate, but currently, we cannot use it as
the our DB `Connection` would have to be `Send`. This PR is an
introduction and quality of life changes for the users of the CLI and
for us developers, as we now won't have to look at black and white text
only. I want to have a config file to personalize the color pallets,
that will be made in a following PR.
