fix: enable Gemini file writing by passing --yolo and -p flags

GeminiRunner.buildArgs was missing --yolo (auto-approve all tools)
so the gemini CLI only registered 3 tools (read_file, write_todos,
cli_help) and write_file was not available. Agents that needed to
create files silently failed (exit 0, no files written).

Also switch instructions from bare positional arg to -p flag, which
is required for non-interactive headless mode.

Update preamble tests to match file-based summary approach
(CLAUDOMATOR_SUMMARY_FILE) kept from the merge conflict resolution.
