Subject: [PATCH] Increase heap size for checkstyleNohttp task

On a developer machine, the nohttp check scans the whole project
directory, and things like local git worktrees can add enough extra
content on disk to push the task past its previous 1g heap limit,
causing an OutOfMemoryError. This goes beyond what was addressed by
excluding the .claude folder from nohttp scanning in 48971139c02.

This commit raises the heap size for checkstyleNohttp specifically
to 1536m, leaving the limit for other Checkstyle tasks unchanged so
as not to increase memory pressure on CI.
