Adds a Rounded Crop image tool for logo, favicon, and app-icon work. It masks the framed square to a rounded rectangle (with a corner-radius control) or an iOS-style squircle, reusing circle-crop's zoom/offset framing, border ring, background fill, and output-size options. Includes translations across all 21 locales.
Closes#601
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.
Adds a dedicated remove-gif-background AI tool: removes the background from an animated GIF, WebP, or APNG frame by frame and reassembles a transparent (or composited) animation in WebP, APNG, or GIF, with full per-frame effects. Reuses the background-removal bundle. Verified end-to-end with the real rembg model.
Closes#496.
The nightly Schemathesis job failed with a schema-loading error:
'unacceptable character #x0080: control characters are not allowed'. The
served openapi.yaml contained 215 em dashes (U+2014) and box-drawing
section dividers (U+2500); Schemathesis's strict YAML parser mis-decodes
those multi-byte UTF-8 sequences as C1 control chars and refuses to load
the schema, so no fuzz checks ran. (PyYAML is lenient, which is why the
local yaml.safe_load check passed.)
Replace every non-ASCII char with ASCII '-'. This also clears an
em-dash style-rule violation. Add a docs.test.ts guard asserting the
served spec is ASCII-only, with a clear message, so this can't regress.
Pre-existing issue (the dashes predate this branch); surfaced while
verifying CI is green.
