Runs on push to master only (not PRs — too slow). Scoped to the mutator and filter packages whose tests are plain unit tests; cmd/ is excluded because its tests re-invoke the binary, and internal/annotation is excluded due to existing build errors. exec-timeout is 30s per mutant, job timeout is 45 minutes. continue-on-error keeps the result informational until a baseline score is established. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Add 4 targeted test cases to internal/filter that together cover the specific AST paths previously left untested: a 1-arg make (kills the len>1 → >=1/true variants), unary negation of a complex sub-expression (kills else-branch removal), a nested CallExpr with two int args (kills loop-break and statement-remove on the arg-recursion loop), and unary on float literals (kills the token.INT → true comparison mutation).

- Remove continue-on-error from mutation workflow (the tool exits 0 regardless of score, making the flag redundant and misleading) - Document all excluded packages and the exit-0 behaviour in a comment - Gitignore mutation run artifacts (binary, report.json/html, *.go.new) - Remove mutant-specific comments from test table entries; keep only the parser-validity note on the 1-arg make case Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

This PR adds a GitHub Actions workflow that runs go-mutesting on its own packages, and adds four new test cases to
internal/filterthat kill all 8 mutants that were left alive when we ran the tool against itself.
