• Use Sorbet typed: strict in all (non-package) files in Homebrew organisation #17297

[Copilot]

Pull request overview

This pull request migrates Library/Homebrew/debrew.rb from typed: true to typed: strict Sorbet mode, which is part of the ongoing effort tracked in issue #17297. The changes add comprehensive type signatures to satisfy Sorbet's strict typing requirements while maintaining the existing functionality of the debugging helper module for Homebrew formulae.

Key Changes:

• Upgraded Sorbet typing level from typed: true to typed: strict
• Added type signatures for all methods in the Debrew::Formula module and Debrew::Menu class
• Converted Entry from a regular Ruby Struct to a T::Struct for better type safety
• Added proper type annotations for module-level instance variables and class methods
