feat: add module, tool execution, and agent response attributes (#13)

* chore: Improve repository structure with templates and documentation organization

- Add CODEOWNERS for automatic review assignment
- Add issue templates (bug report, feature request)
- Add pull request template with comprehensive checklist
- Add pre-commit config with gitleaks, uv-lock, and ruff
- Improve release-drafter.yml with more categories and better organization
- Move AUTOMATION.md and ROADMAP.md to docs/ directory
- Remove MERGE_BOT_GUIDE.md (content moved to AUTOMATION.md in English)
- Update AUTOMATION.md with /update command documentation
- Move Development section from README to CONTRIBUTING.md
- Update ROADMAP version from v0.2.0 to v1.1.0
- Update all documentation references to new file locations

* Fix merge-bot update command checkout issue

The update command was failing because the checkout action wasn't
specifying which repository to checkout from. This caused it to only
fetch the default branches and not the PR branch.

Added 'repository' parameter to the checkout action to explicitly
specify the head repository, fixing the branch checkout issue.

Same fix as applied to msgspec-ext repository.

* feat: add module, tool execution, and agent response attributes

Add new attribute setters for:
- Module attributes (name, type) for specialized visualizations
- Extended tool attributes (execution type, protocol)
- Extended agent attributes (response content)

These attributes enable better categorization and visualization
of AI operations in the msgtrace frontend.
