Rewrite store JSDoc, split quote/order into modules, and generate typed API docs

- Rewrite JSDoc across all store methods to document the actual async
  methods (real params, returns, throws) instead of the internal wrappers
- Split quote/order into individual module files backed by shared
  manifestDoc helpers; remove the createStore factory and thin wrappers
- Deduplicate manifest line helpers into src/store/manifestLines.js
- Extend generate-api-doc.js to render parameter/return/throws types and
  emit per-namespace API.<module>.md files with an API.md index
- Regenerate all API docs
