- Isolate skills injection using a temporary directory mapped via
GEMINI_CLI_HOME, mirroring the claude-local sandbox approach
instead of polluting the global ~/.gemini/skills directory.
- Update the environment probe to use `--output-format stream-json`
so the payload matches the downstream parseGeminiJsonl parser.
- Deduplicate `firstNonEmptyLine` helper by extracting it to a
shared `utils.ts` module.
- Clean up orphaned internal exports and update adapter documentation.
