fix(logger): add type assertions for Console stream properties

Fixes TypeScript compilation errors when accessing private Console stream properties (_stderr, _stdout):
- assert(): Cast message parameters to proper types for console.assert
- progress(): Add type assertion for streamObj write method
- clearLine(): Add type assertions for TTY properties (isTTY, cursorTo, clearLine, write)

These properties are not properly typed in Node.js Console type definitions, so explicit type assertions are needed for type safety.
