fix: project validation not working on windows

Fix ESM path handling on Windows

Issue:
ERR_UNSUPPORTED_ESM_URL_SCHEME error occurs on Windows when validating MCP projects due to non-URL file paths in dynamic import().

Cause:
Windows absolute paths (e.g., C:\...) aren't valid ESM URLs. At https://github.com/QuantGeekDev/mcp-framework/blob/eb3a7bf/src/cli/utils/validate-project.ts#L9-L11, the original code used:

await import(packageJsonPath)

which fails on Windows because ESM requires file:// URLs.

Fix:
Use fs.readFile + JSON.parse instead of dynamic import:

const package_json = JSON.parse(await readFile(packageJsonPath, "utf-8"));
