perf: 使用非捕获分组优化 KuRootView 正则的匹配

[xiaohe0601]

正则改为非捕获组，可能会提升一点点性能

Summary by CodeRabbit

• Refactor

Walkthrough

Updated a regex in src/root.ts to use a non-capturing group for matching self-closing or closing root tags. The replacement behavior to "" remains unchanged. No exported/public API changes.

Changes

Cohort / File(s)	Summary
Regex tweak in root processing src/root.ts	Switched capturing group to non-capturing in the root tag regex while preserving match semantics and replacement logic to "".

Poem

I nibble on regex, crisp and neat,
Turn capture to non-capture—light on its feet.
The slot still shines where roots once grew,
A tiny hop, the same view through.
Thump-thump! Code is tidy, fast, and sweet.

Tip

👮 Agentic pre-merge checks are now available in preview!

Pro plan users can now enable pre-merge checks in their settings to enforce checklists before merging PRs.

• Built-in checks – Quickly apply ready-made checks to enforce title conventions, require pull request descriptions that follow templates, validate linked issues for compliance, and more.
• Custom agentic checks – Define your own rules using CodeRabbit’s advanced agentic capabilities to enforce organization-specific policies and workflows. For example, you can instruct CodeRabbit’s agent to verify that API documentation is updated whenever API schema files are modified in a PR. Note: Upto 5 custom checks are currently allowed during the preview period. Pricing for this feature will be announced in a few weeks.

Please see the documentation for more information.

Example:

reviews:
  pre_merge_checks:
    custom_checks:
      - name: "Undocumented Breaking Changes"
        mode: "warning"
        instructions: |
          Pass/fail criteria: All breaking changes to public APIs, CLI flags, environment variables, configuration keys, database schemas, or HTTP/GraphQL endpoints must be documented in the "Breaking Change" section of the PR description and in CHANGELOG.md. Exclude purely internal or private changes (e.g., code not exported from package entry points or explicitly marked as internal).

Please share your feedback with us on this Discord post.

21-21: Allow optional whitespace before closing tag and make the regex global

rg output shows matches in examples/src/KuRoot.vue:1 and README.md:8 — the current regex misses cases like <KuRootView>\n</KuRootView>.

Use:
const rootTagNameRE = /<(KuRootView|ku-root-view)(?:\s*/>|>\s*</\1>)/g
