fix(rules-injector): remove dead batch code, add .sisyphus support

- Remove non-functional batch tool handling (OpenCode has no batch tool)
- Keep working direct tool call path (read/write/edit/multiedit)
- Apply same cleanup to directory-agents-injector and directory-readme-injector
- Add .sisyphus/rules directory support
