chore(scripts): require KIMI_CODE_REPO in sync:web, drop dead copy-web-dist

- sync-web-to-kimi-code.mjs: KIMI_CODE_REPO is now required (no more ../kimi-code-2 default), the target is validated as a kimi-code checkout, errors are in Chinese, and a reminder to open a PR in the kimi-code repo prints after a successful sync
- Remove apps/desktop/scripts/copy-web-dist.mjs and the web-dist .gitignore entry: the desktop renderer builds from src/renderer into desktop-dist, so the web-dist copy flow is dead
- README.md / AGENTS.md updated to match
