Delete/Update fail with non-integer primary key

[achrafash]

Thanks for the amazing work as always! (was a user of sqlite-vss before)

Not sure if related to #53, but updating/deleting records when using a string as primary key fails (“unknown error”).

Configuration:

create table articles (
   id text primary key,
   headline text,
   url text
);

create virtual table if not exists vec_articles using vec0(
   article_id text primary key,
   embedding float[384],
);

Inserting and selecting work fine, but updating or deleting throws the following error:
