• Pass explicit keywords to FormulaAuditor.new and Style.check_style_json so brew typecheck catches a mistyped keyword. .compact and keys added after the hash literal hid them from Sorbet, so a typo only failed at runtime.
• Drop FormulaAuditor's display_cop_names:, which nothing has passed since --display-cop-names became a hidden no-op.
• Cover the cops that --only-cops, --except-cops, --new and --strict select in unit tests.

Summary

Summary by CodeRabbit

• Bug Fixes
  • Formula style audits now respect the selected checks and exclusions across default, strict, new-formula, and explicit cop-selection options.
  • Style-audit findings now show the offense message without a cop-name prefix, making the reported issue more direct.

The audit command now selects and passes style cop options directly. FormulaAuditor no longer accepts display_cop_names and reports offense messages without cop-name prefixes.

Changes: Formula style audit

Layer / File(s)	Summary
Cop option selection and forwarding Library/Homebrew/dev-cmd/audit.rb, Library/Homebrew/test/dev-cmd/audit_spec.rb	Audit#run selects cop exclusions based on the audit flags and passes style options directly to Style.check_style_json. Tests cover default, strict, new, only-cop and except-cop cases.
Formula auditor style reporting Library/Homebrew/formula_auditor.rb	FormulaAuditor removes the display_cop_names option. audit_style passes each offense message to problem without a cop-name prefix.
