Simple benchmark

[webdevred]

Summary

• Added jbeam-edit-bench using Criterion in tools/bench/Main.hs to measure:
  1. format-only
  2. transform+format
• Benchmarks load .hs AST files from examples/ast/jbeam and examples/ast/jbfl, covering minimal and complex cases.
• Updated cabal.project.ci and package.yaml to define benchmark targets and support +transformation flag.
• Integrated benchmarks into release and latest-deps workflows:
  • Release workflow runs benchmarks when +transformation flag is set.
  • Latest workflow always runs benchmarks to validate performance on newest GHC/dependencies.
• Project scripts (configure_project.sh, prepare_installer.sh) updated to ensure benchmarks build and run correctly.
• IDE support for bench/Main.hs added in hie.yaml and Emacs .dir-locals.el.
