Vue single-file component (SFC) extractor

[idomy]

Goal

Extract user-facing strings from Vue SFCs (.vue), the same way we do for React/TSX.

Scope for a first PR

Start with the <template> block only:

• text nodes (<p>Hello</p>)
• a curated attribute allow-list (title, placeholder, aria-*, ...)
• skip :class / class and directives

Pointers

• Parse .vue with @vue/compiler-sfc (template AST) instead of Babel.
• Mirror src/extract.mjs; keep the same record shape {file,start,end,kind,text} so apply and verify work unchanged.
• Larger than the other issues — labeled help wanted. Ask questions on the issue before diving in.
