fix(options): src match

[ryuujo1573]

Given input:

{
    projectRoot: "./",
    srcEntryFile: "src/index.ts",
    srcMatch: "src/",
}

Expected: ctx.file from handleHotUpdate should be matched by "./src/" (both get expanded)
Actual: the dot "." is not recognised properly as a qualified matching path

About cross-platform compatibility: this works fine, for "node:path" resolves path well.
