Compile diagnostics

@elfui/vite-plugin will give build-time diagnostics for macro components.

Common diagnoses:

Scene	Processing
Import macro API but not export defineHtml()	Add component export or delete macro import
Use removed macro aliases	Change to new APIs such as defineProps / defineEmits
The pragma position is illegal	Move to the top of the file or use normal .ts export

During Vite startup, ElfUI also checks the exact beta versions and compiler protocols of Core, Compiler, and Vite Plugin. A mismatch stops before the first template compile with ELF_VITE_VERSION_MISMATCH or ELF_VITE_PROTOCOL_MISMATCH, resolved paths, a repair command, and a Vite cache cleanup hint.

strict mode

elfuiMacroPlugin({
  strictDiagnostics: true,
  templateTypeCheck: true,
});

strictDiagnostics is suitable for CI; templateTypeCheck is suitable for component libraries and pre-beta quality gates.
