08c1e13679 Merge 'Handle count(*)' from Vegard Stikbakke 
This PR adds support for `count(*)`. I did not find any other functions than `count` which expect a `*` argument yet, but I'm sure there are some?

Surprisingly (to me) I did not need to make any changes to `translate_expr`, only to `analyze_expr`.

```
limbo> SELECT count(id) FROM users;
2
limbo> SELECT count(*) FROM users;
2
limbo> SELECT count(*) FROM users where id = 1;
1
limbo> SELECT count(id) FROM users where id = 1;
1
```

Other aggregation functions such as sum fail, since they expect a specific column:
```
limbo> select sum(*) from users;
Parse error: sum bad number of arguments
```

Closes #285

3f96b1d798 Merge 'Initial pass on Python API' from Jean Arhancet 
This pull request introduces the initial setup for the Python bindings
(#248).

- Setup Configuration: Added the Python binding stack, including the
  `pyo3 `crates, `pyproject.toml`, `build.rs`, and other necessary
  files.

- Database Class: Implemented the Database class with a constructor to
  establish a connection and a query function to execute SQL queries.

- Testing: Created `database.db` with a sample users table and two
  entries, as outlined in README.md, and added three pytest functions to
  validate the Python output.

Closes #276

d4d7042373 Merge 'Use the correct integer PK column idx as the row-id alias' from GV 
This pull request addresses [issue #256](https://github.com/penberg/limbo/issues/256).

However, it currently breaks insertions into tables that lack a row-id
alias due to the NewRowId not being implemented yet. I have created an
[issue](https://github.com/penberg/limbo/issues/275) to track this
problem and will submit a separate pull request to resolve it soon.
