Document Gemini CLI slash updates

* feat: add Gemini CLI support with TOML-based slash commands

- Add GeminiSlashCommandConfigurator for .gemini/commands/openspec/
- Register Gemini CLI in AI_TOOLS config and slash command registry
- Generate TOML files with description and prompt fields
- Add comprehensive test coverage for Gemini CLI integration
- Update README to list Gemini CLI under Native Slash Commands
- Remove Gemini CLI from AGENTS.md compatible list (now native)

Implements GitHub issue #248

* [add]

* feat: address PR feedback - remove changeset and add update test

- Remove .changeset/add-gemini-cli-support.md as requested by maintainer
- Add test for Gemini CLI TOML update/refresh path
- Test verifies that existing TOML files are properly updated when running init again

Addresses feedback from TabishB in PR #256
