tabnas-csv 0.6.2

// Cross-runtime conformance, driven by the shared `test/spec/*.tsv`
// fixtures at the repository root (see ../../test/AGENTS.md).
//
// The fixture loader, the escape codec, the `ERROR:<code>` contract and
// the row loop all come from tabnas_support, whose TypeScript half
// `ts/test/parity.test.ts` and Go half `go/parity_test.go` run the SAME
// files, so the three implementations cannot drift without one of them
// going red, and neither can the loaders.
//
// What is left here is only what is specific to csv: how to build the
// parser for a row's `opts` column, and how to flatten a result.
