SnapOtterandGitHub f858c4cea0 feat: clearer, disambiguated tool names across all surfaces (#520)
Renames 18 ambiguous or hard-to-search tool names so image tools self-qualify like the other modalities ("Compress" becomes "Compress Image"), and cleans up a few awkward names. Propagated across search (constants.ts), display (en.ts + 20 locales), the OpenAPI base spec + 20 locale specs, and the docs tool-page headings in 21 languages. Removes the duplicate "Normalize Audio" summary shared by the video and audio endpoints. Tool ids and routes are unchanged, so no API paths or bookmarks break.

Notes

  • 正值增大音量,负值减小音量。
  • 较大的正增益可能导致削波。可使用 normalize-audio 进行响度安全的电平调整。
  • 输出通常保留输入容器格式。AAC 输入会写成 M4A,不受支持的仅解码输入会回退为 MP3。
