Changelog of @hackage/hasql-effectful 0.2.0.0

Revision history for hasql-effectful

Breaking: drop support for any GHC older than 9.12. The library is now tested only with GHC == 9.12.*.
Modernize toolchain: devShell uses ghcWithPackages, with treefmt-nix and git-hooks.nix integration.
Bump bounds: base >= 4.21, effectful >= 2.5, hasql >= 1.10, hasql-pool >= 1.4, hasql-transaction >= 1.2.
Move the example to a cabal flag (-fexamples) so the library builds without pulling in hasql-transaction by default.
Update the example to use the new Hasql.Pool.Config-based Hasql.Pool.acquire introduced in hasql-pool 1.0.
