Formatter line endings

Set formatter.endOfLine in vize.config.* for CLI and editor formatting:

import { defineConfig } from "vize";

export default defineConfig({
  formatter: { endOfLine: "auto" },
});

The modes are "lf" (default), "crlf", "cr" and "auto". Auto selects the first source terminator; an adjacent CRLF selects CRLF, a lone CR selects CR, and LF or no terminator selects LF. A Vue file selects its layout endings once for all template, script and style blocks. Explicit modes take precedence over the input's layout. Authored raw text keeps its original bytes.

Node and WASM accept the same values in their existing formatter options:

import { formatSfc } from "@vizejs/native";

const source = "<template>\r\n<p>hello</p>\n</template>\n";
const result = formatSfc(source, { endOfLine: "auto" });
const again = formatSfc(result.code, { endOfLine: "auto" });
// again.changed === false

Node rejects unsupported mode strings with InvalidArg and non-string values with StringExpected. Both diagnostics name the endOfLine field. Formatting returns the existing code and changed fields.
