fix(imagekit): stop double-encoding hyphens in aspect ratio values

[cpruijsen]

Summary

generate now decodes formatter output before URLSearchParams.set, so the query string encodes once. The decoded tr is ar-9-16, matching ImageKit's documented form.

ImageKit ar values such as 9-16 were written as ar-9%252D16 in tr. After one query decode ImageKit sees ar-9%2D16, which is not a valid aspect ratio.

extract keeps hyphens that appear inside values, so official URLs like tr:ar-4-3,w-400 round-trip as ar: "4-3" instead of ar: "4", and transform() of a generated ar-9-16 URL no longer truncates the ratio.

Fixes #195.

Decision

Decode in ImageKit generate, and re-encode extra hyphens only in ImageKit extract. Alternative: change the shared operations parser to keep everything after the first key/value separator. That shared change made Uploadcare parse quality/lighter/ as "lighter/" (trailing / is their key/value separator). Can switch if you would rather fix the parser once for every provider.

Test plan

• deno test src/providers/imagekit.test.ts
• New tests fail without the source change and pass with it (generate is not %252D; extract of ar-9-16 / ar-4-3; transform keeps ar-9-16)
• deno check src/
• deno test src/ (85 tests)
• Optional: request ?tr=w-640,ar-9-16 against a real ImageKit image and confirm the crop is 9:16
