ZhenYi afad0ab55d feat(agent): implement built-in skills system (16 skills)
Add built-in skills with trigger-based activation system:

Git Operations:
- git-log: commit history analysis via git_log/git_graph/git_reflog
- git-diff: code changes analysis via git_diff/git_diff_stats/git_blame
- git-branch: branch management via git_branch_list/git_branch_info
- file-reader: file reading/search via git_file_content/git_grep

Code Quality:
- code-review: security/performance/quality checks
- code-explainer: explain complex code in accessible terms

Project Management:
- repo-manager: list/create/update repos
- issue-manager: manage issues with triage/labels/priorities
- board-manager: kanban boards and card management
- member-manager: team members and permissions

Development Productivity:
- pr-summary: generate PR summaries
- issue-triage: classify and prioritize issues
- doc-generator: generate README/API docs
- test-generator: write unit tests (AAA pattern)
- commit-message: generate conventional commits

Utilities:
- http-requester: HTTP requests and API testing

Skills integrated via PerceptionService with active/passive/auto triggers
Built-in skills automatically available to all projects
Database skills override built-in skills with same slug
