✨ feat(newapi): vendor/model sync; K/M context; move ratios path

Add a NewAPI model-management sync suite and restructure outputs:

- Endpoints (under /api/newapi/):
  - vendors.json — rows aligned to `vendors` table
  - models.json — rows aligned to `models` table
  - ratio_config-v1-base.json — pricing ratios payload
- build.js:
  - Centralize all NewAPI generation into one block
  - Add helpers: buildNewApiSyncPayload(), buildNewApiTags(), formatTokensToKM()
  - Include context size in tags using K/M notation (e.g., 128K, 1M; no prefix)
  - Unify Markdown table limits via K/M formatting (1,000K becomes 1M)
- docs:
  - Update docs/index.md to list new endpoints and new ratios path
  - Update README.md & README.zh-CN.md links/descriptions

BREAKING CHANGE: pricing ratios endpoint moved from
  /api/newapi-ratio_config-v1-base.json
to
  /api/newapi/ratio_config-v1-base.json
(Update consumers accordingly; payload shape unchanged.)
