fix(benchmark): skip-trust for headless gemini + drop release metadata

Pass --skip-trust so temp/untrusted workdirs work in headless
benchmarks (mirrors Codex --skip-git-repo-check). Revert VERSION,
CHANGELOG, and package.json bumps — leave release bookkeeping to
maintainers / /ship, matching community PR practice.

  * Key differences from Codex session-runner:
  * - Uses `gemini -p` instead of `codex exec`
  * - Output is NDJSON with event types: init, message, tool_use, tool_result, result
- * - Uses `--output-format stream-json --yolo` instead of `--json -s read-only`
+ * - Uses `--output-format stream-json --yolo --skip-trust` instead of `--json -s read-only`
+ *   (`--skip-trust` required for headless/untrusted cwds; see gemini trusted-folders docs)
  * - No temp HOME needed — Gemini discovers skills from `.agents/skills/` in cwd
  * - Message events are streamed with `delta: true` — must concatenate
