Pull request overview
Updates Cabal-syntax on the 3.18 branch so that CabalSpecV3_18 is treated as the latest supported Cabal specification, aligning cabalSpecLatest with the spec versions that Cabal-syntax 3.18 already parses and preventing cabal-install from misclassifying cabal-version: 3.18 Simple packages as “future format”.
Changes:
- Bump
cabalSpecLatestfromCabalSpecV3_16toCabalSpecV3_18.

Cabal-syntax 3.18 recognizes CabalSpecV3_18, but cabalSpecLatest remained CabalSpecV3_16. cabal-install consequently treated Simple packages that declare cabal-version 3.18 as future-format packages and selected an external setup script. Move the supported-version boundary to CabalSpecV3_18 so these packages use the in-process setup path. Fixes haskell#12271
