- Fix WASM size gate: 3 MB → 3.5 MB to match size_test.go - Fix dependencies: remove stale replace directive, add go-io and go-log - Add error handling and I/O conventions to coding standards - Add tests: reader error (cmd/codegen), duplicate tag dedup, bundle error propagation (codegen) — coverage: codegen 89→96%, cmd/codegen 71→78% Co-Authored-By: Virgil <virgil@lethean.io>
