fix: support Space key activation

[nrps9909]

Summary

• activate focused rate items with Space as well as Enter
• prevent the Space key from scrolling the page during activation
• cover both keyboard paths and their default-prevention behavior

Why

Each enabled star exposes role="radio" and is focusable, but its keyboard handler only recognized Enter. Space is the expected activation key for radio controls, so keyboard users could focus a star and still fail to select it with the conventional key.

The regression test fails on the base commit because the Space event does not produce the second onChange call and is not cancelled.

Validation

• npm test -- --runInBand (2 suites, 40 tests, 7 snapshots)
• npm run tsc
• npm run lint (no errors; one pre-existing Rate.tsx exhaustive-deps warning)
• npm run compile
• git diff --check

Overlap audit

I checked every currently open PR that changes src/Star.tsx. None changes the key activation handler or adds Space activation. The recent #218 touches separate rendering/style lines for exact-value display.

AI assistance disclosure: Codex was used to trace the keyboard path, audit open PR diffs, and draft the focused regression test. The behavior and validation were checked locally.

Walkthrough

Star 组件现在响应 Enter 和空格键。两个按键都会阻止默认行为，并触发 onClick。键盘测试覆盖这两种按键。
