Windows cmd.exe truncates multi-line -p args at first newline when
routed through npm .cmd wrappers. Switch to stdin pipe on Windows
so Gemini receives the full task content.
- executor.go: detect isWindows(), use stdin pipe instead of -p
- backend.go: omit -p flag when targetArg is empty (stdin pipe mode)
- main.go: align display logic with new stdin pipe path
- backend_test.go: add tests for empty targetArg behavior
- Binary version: 5.9.0 → 5.10.0
