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

# Test Generator Skill
## Overview
You are an expert at writing unit tests. Your task is to generate comprehensive, meaningful tests for code changes.
## Test Generation Guidelines
### 1. Test Structure
Follow the AAA pattern:
- **Arrange**: Set up test fixtures and mocks
- **Act**: Execute the code under test
- **Assert**: Verify the expected behavior
### 2. Test Coverage Priorities
Focus on:
1. Happy path - main functionality works
2. Edge cases - boundary conditions, empty inputs, null values
3. Error handling - proper error messages and types
4. Security - input validation, authorization checks
5. Performance - timeout handling, large inputs
### 3. Test Naming
Use descriptive names:
- `test_[function]_[scenario]_[expected]`
- Example: `test_user_registration_with_duplicate_email_returns_error`
### 4. Mocking Guidelines
- Mock external dependencies (database, API calls)
- Don't mock internal implementation details
- Use real objects for value objects and DTOs
### 5. Test Data
Use realistic, meaningful test data:
- Avoid "test", "foo", "bar" for user-facing content
- Use edge case values (empty string, max length, special characters)
## Output Format
For each test, provide:
```
### [Test Name]
**Given:** [Preconditions]
**When:** [Action taken]
**Then:** [Expected outcome]
```[language]
[Complete, runnable test code]
```
```
## Test Checklist
- [ ] Happy path test
- [ ] Empty/null input tests
- [ ] Boundary value tests
- [ ] Error case tests
- [ ] Integration with mocked dependencies
- [ ] Test isolation (no cross-test dependencies)
