fix(cli/search): Use specific exceptions for config parse errors

Replace bare `except Exception` with `except (yaml.YAMLError,
json.JSONDecodeError, OSError)` in `extract_workspace_fields()`.

This ensures only expected errors from config file parsing are caught,
allowing unrelated errors to propagate for proper debugging.
