Compile sqlite with SQLITE_ENABLE_UPDATE_DELETE_LIMIT

[alindeman]

I have a project that runs sqlite queries in the form DELETE FROM X ... LIMIT Y. When I was using a Debian-provided Python, these queries worked properly. But when I used a Python installed by uv (via this project), the queries failed with a syntax error.

I tracked it down to a difference in the compile-time options for sqlite. Debian compiles sqlite3 with -DSQLITE_ENABLE_UPDATE_DELETE_LIMIT=1 but this project dooes not.

Are you all open to adding this compilation flag?

This option enables an optional ORDER BY and LIMIT clause on UPDATE and DELETE statements: https://sqlite.org/compile.html#enable_update_delete_limit

It is enabled by default in the Debian sqlite3 package: https://sources.debian.org/src/sqlite3/3.46.1-8/debian/rules#L51

Unfortunately I realized this won't work as written because we currently build sqlite3 from the amalgamation and this is one of the few compile-time options that cannot be built using the stock amalgamation.

I will mull over whether it is worth reworking this build process to build the amalgamation from scratch for this option.
