codeguard Updates & Release Notes

1.0.0 (2026-07-16)

⚠ BREAKING CHANGES

promote performance rules to their own opt-in check section (#41)

the performance rules' ids renamed from quality.* to performance.* (quality.n-plus-one-query -> performance.n-plus-one-query, quality.go.alloc-in-loop -> performance.go.alloc-in-loop, quality.sync-io-in-request-path -> performance.sync-io-in-request-path, quality.unbounded-goroutines-in-loop -> performance.unbounded-goroutines-in-loop, plus the typescript/javascript mirrors and quality.python.sync-io-in-async). Their detect_* toggles moved from quality_rules to performance_rules, and the section is opt-in: set checks.performance: true to keep running these rules, and update any waivers or baselines that reference the old ids.
