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.

Closes #274

707d1a0705 Merge 'Update Flake and add Darwin link flags' from Ethan Niser 
This pull request:

 - updates the nix flake to include tcl 8.6 addressing #243

 - updates the nix flake to add the darwin "core foundation" lib

 - updates the make flake to link the core foundation lib on darwin

I was previously unable to run `make test-sqlite3` with this error:
https://gist.github.com/ethanniser/5b96888637da6ea9e9d56dcc3af9b573

But now it is able to run.
