chore: exclude asset catalogs from CodeRabbit review

Icon-import PRs change hundreds of files, and although CodeRabbit already skips
the binary PNGs, the imageset Contents.json files alone put PR #6 at 124 changed
files against a limit of 100 — so the review was skipped entirely and the Swift
changes went unreviewed.

Filtering out **/*.xcassets/** leaves only the source files, 19 in that PR.
Nothing is lost: imageset Contents.json is generated by Xcode or by the Figma
export tooling and is never hand-edited.
