test: comprehensive test coverage for v0-v4 agents

Unit tests (25 tests):
- TodoManager edge cases: empty list, status transitions, missing fields, invalid status, render format
- v3 subagent: AGENT_TYPES structure, get_tools_for_agent, get_agent_descriptions, Task tool schema
- v4 skills: SkillLoader init, parse valid/invalid SKILL.md, get_skill_content, list_skills, Skill tool schema
- Security: safe_path path traversal prevention
- Config: ANTHROPIC_BASE_URL support

Integration tests (21 tests):
- v0: bash echo, bash pipeline
- v1: read_file, write_file, edit_file, read_edit_verify
- v2: TodoWrite single task, TodoWrite multi-step
- Error handling: file not found, command fails, edit string not found
- Workflows: create Python script, find and replace, directory setup
- Edge cases: unicode content, empty file, special chars, multiline edit, nested directory, large output, concurrent files
