Changelog

Unreleased

Initial release with 35 configurable Credo checks for generated-code mistakes, error handling, test quality, shared state, structural limits and query regressions. See docs/checks.md for behavior and parameters.
Preserved EmptySetupBlock, RuntimeEnvDevDefault, SkippedTest and the previously unreleased JustifiedCoverageIgnore from OptimumCredo, including their original copyright notices. See docs/migration.md for the renamed modules.
Added seven advisory regression diff rules and mix kogen.diff_check, suppression and golden-configuration integrity helpers, and the advisory mix kogen.unused_public task.
Added explicit configuration examples and regression coverage for valid lookalikes, lexical scope, framework boundaries and parameter changes. Source-derived identities remain strings rather than allocating atoms.
Require Elixir 1.17 or newer and Credo 1.7.19 or newer within 1.x. Diff analysis and unused-public findings remain advisory and have documented static-analysis limits.
