docs(gitcommit): update docs and config for new gitignore and commit selector features

- remove "🆕" and v2.0 markers from documentation and config comments
- add documentation for gitignore management commands and workflows
- introduce `gitcommit_select_count` option for commit selector in README, config, and docs
- update language lists to use English names (e.g., "Chinese" instead of "简体中文")
- clarify and expand git tool and chat integration documentation
- update config examples to reflect new options and naming conventions
