refactor(mac): converge core/animation.rs and animation/prefix.rs to the shared version

core/animation.rs takes the shared copy (module docs, three serde unit tests) and its one doc comment now reads 'Bezier' like the Windows copy; that text is the description of the CubicBezier branch in schema.json, so schema.json changes in that one line (description only; the Windows schema keeps its text). prefix.rs gets the module docs; the macOS-only AnimationPrefix (no Transparency) is converged in the next revision.

Verified: fast-check macOS (fake CC) cargo check --workspace --all-targets: PASS. jj diff of schema.json: the single description line. macOS tests not run (cannot).
