New recipes implementing SonarQube RSPEC rules with auto-remediation: - S1066 CollapsibleIfStatements: merge nested ifs with && - S1656 RemoveSelfAssignment: remove x = x dead assignments - S3923 AllBranchesIdentical: collapse if/else where all branches match - S1764 SimplifyRedundantLogicalExpression: simplify x && x to x - S1862 RemoveDuplicateConditions: remove dead duplicate-condition branches - S1871 MergeIdenticalBranches: merge identical branch bodies with || - S4143 RemoveUnconditionalValueOverwrite: remove dead map.put overwrites These are part of a cross-language initiative covering Java, Go, C#, JavaScript, and Python with the same rules in each language.

If these recipes are meant to work for all these 5 languages, should we add at least one case for each of the language in each test? |
Resolve conflicts in recipes.csv by keeping all new recipe entries from both branches.
Return directly when a branch has no else, removing the need for the `hasExplicitElse` flag and its follow-up guard.
`SemanticallyEqual` already matches `(a)` with `a`, but returning `b.getLeft()` preserved the surrounding parens. Call `unwrap()` so `(a) && a` simplifies to `a` rather than `(a)`.
Expressions containing method invocations, assignments, increments, or `new` may produce different results across repeated evaluations, so simplifying `iterator.next() && iterator.next()` to `iterator.next()` changes semantics. Only simplify when both operands are side-effect free.
