fix: resolve parameter validation bug in project-discovery tools

- Fixed list_schems_ws, show_build_set_proj, and show_build_set_ws tools
- Changed schema definitions from z.object({...}) to plain object {...}
- Root cause: z.object schema pattern prevented proper parameter parsing
- Added parameter casting for safe property access in list_schems_ws
- Verified fix works through Reloaderoo CLI testing

Tools affected:
- list_schems_ws: workspacePath parameter validation
- show_build_set_proj: projectPath and scheme parameter validation
- show_build_set_ws: workspacePath and scheme parameter validation

This resolves the issue where tools were receiving {signal:{}, requestId:1}
instead of actual user parameters when using z.object schema pattern.
