docs: remove ntk tailwind, document the real dev loop

[next-devin]

Problem

Spark's README and CLAUDE.md document ntk tailwind / ntk tailwind --minify and claim ntk watch auto-compiles Tailwind. Neither is true of released ntk (1.1.1): the tailwind subcommand exists only on an unmerged theme-kit branch, and ntk watch only watches and pushes files (its compile step covers sass/, which Spark does not use). Anyone following the docs hits a hard failure at the first CSS change.

Alex ruled on NextCommerceCo/theme-kit#31 that ntk stays frontend-framework-agnostic, so the fix is to remove the references rather than wait for a release.

What changed

• Removed the two ntk tailwind rows from the README command table and the CLAUDE.md dev block.
• Corrected the ntk watch description in both files: it watches and pushes, and the Tailwind compile comes from the standalone binary.
• Promoted make dev (Tailwind watcher + ntk watch in parallel) from its Legacy label to the standard dev loop, which matches what the Makefile actually does. Added make watch to the README table for the two-terminal setup, and dropped the stale Legacy labels on make css / make build.
• Added one line to CLAUDE.md recording the decision with a pointer to theme-kit#31.

Verification

• grep -rn 'ntk tailwind' README.md CLAUDE.md docs/ is clean.
• python3 -m unittest discover -s tests passes.
• Command descriptions checked against the Makefile targets and the released ntk parser.

Part of the storefront theme Epic (NextCommerceCo/skills#29). theme-kit#31 can close once this lands; the remaining ntk tailwind references in the Shopify guide are covered by NextCommerceCo/guides#38.
