🔗 docs(readme): update documentation links to new site routing

Keep new-site links (/{lang}/docs/...) where matching pages exist in the current docs repo
Revert links that have no equivalent in the new docs to the legacy paths on doc.newapi.pro:
Google Gemini Chat
Midjourney-Proxy image docs
Suno music docs
Apply the same rule consistently across all README translations (zh/en/ja/fr)

- Replace legacy `docs.newapi.pro` paths with the new `/{lang}/docs/...` structure across all README translations
- Point key sections (installation, env vars, API, support, features) to their new locations
- Ensure language-specific links use the correct locale prefix (zh/en/ja) and keep FR aligned with English routes

fix: 模型设置增加针对Vertex渠道过滤content[].part[].functionResponse.id的选项，默认启用

Tighten oversized request handling across relay paths and make error matching reliable.

- Align `MAX_REQUEST_BODY_MB` fallback to `32` in request body reader and decompression middleware
- Stop ignoring `GetRequestBody` errors in relay retry paths; return consistent **413** on oversized bodies (400 for other read errors)
- Add `Unwrap()` to `types.NewAPIError` so `errors.Is/As` can match wrapped underlying errors
- `go test ./...` passes

🛡️ fix: prevent OOM on large/decompressed requests; skip heavy prompt meta when token count is disabled

Clamp request body size (including post-decompression) to avoid memory exhaustion caused by huge payloads/zip bombs, especially with large-context Claude requests. Add a configurable `MAX_REQUEST_BODY_MB` (default `32`) and document it.

- Enforce max request body size after gzip/br decompression via `http.MaxBytesReader`
- Add a secondary size guard in `common.GetRequestBody` and cache-safe handling
- Return **413 Request Entity Too Large** on oversized bodies in relay entry
- Avoid building large `TokenCountMeta.CombineText` when both token counting and sensitive check are disabled (use lightweight meta for pricing)
- Update READMEs (CN/EN/FR/JA) with `MAX_REQUEST_BODY_MB`
- Fix a handful of vet/formatting issues encountered during the change
- `go test ./...` passes
