fix: correct WIT file path structure for TinyGo components

CRITICAL FIX: TinyGo and wasm-tools expect WIT files in wit/ subdirectory
with the original filename rather than flattened as component.wit.

Changes:
- Modified setup_go_module_action to place WIT file at wit/file-operations.wit
- The prepare_workspace_action already handles creating parent directories automatically
- This resolves "failed to read path for WIT [wit/file-operations.wit]" errors
