Support formatted Vue Pug template tags

[cuishuang]

Summary

Vue files are passed through the Vue preprocessor, which detects <template lang="pug"> blocks and runs the Pug preprocessor on their contents.

The existing regular expression only matched the most compact opening tag form. It missed valid Vue template tags when lang had surrounding whitespace, when the opening tag spanned multiple lines, or when other attributes were present.

This change broadens the opening-tag detection while preserving the existing body replacement behavior. Pug preprocessing now works for formatted template tags and still ignores unrelated attributes such as data-lang.

Test plan

• cargo test -p tailwindcss-oxide
• rustfmt --check crates/oxide/src/extractor/pre_processors/vue.rs

All Oxide and scanner tests pass.

Walkthrough

Vue template extraction now accepts attributes before or after lang, flexible whitespace, and single- or double-quoted values. Quoted attribute contents, including > and lang-like text, do not end the opening tag or select Pug preprocessing. Capture handling reads the language and template body from updated capture groups. Tests cover these parsing cases and unquoted boolean-style attributes.
