Add Prettier formatting checks

[cnluzhang]

Summary

• pin Prettier 3.9.6 and establish a repository-wide formatting baseline
• enforce format:check in pull-request CI, release validation, and prepublishOnly
• preserve the existing bilingual Markdown policy: English prose wraps at 80 columns, Chinese *-zh.md prose remains unwrapped, and embedded code blocks stay hand-formatted
• document the formatter workflow for contributors and agents

This is a formatting and developer-tooling change with no intended CLI runtime behavior change.

Validation

• npm run format:check
• prettier --debug-check .
• npm run lint
• npm run typecheck
• npm test
• npm audit --audit-level=moderate
• npm pack --dry-run
• npm run prepublishOnly
• actionlint .github/workflows/ci.yml .github/workflows/release.yml
• git diff --check

Markdown parsing was also compared before and after formatting; outside the intentional formatter documentation updates, the rendered document structure is unchanged.

Pull request overview

Establishes Prettier as the repo-wide formatter, applies a formatting baseline across source/docs/examples, and enforces formatting checks in CI and release/publish flows. This is a developer-tooling change intended to be behavior-neutral for the CLI.

Changes:

• Pin Prettier 3.9.6, add format / format:check scripts, and introduce a repo .prettierrc.json that preserves the bilingual Markdown wrapping policy.
• Enforce npm run format:check in PR CI, release validation, and prepublishOnly.
• Apply the formatting baseline across CLI code, tests, docs, templates, and examples.
