feat: add new skills for coding standards, continuous learning, detail layout, form layout, project guidelines, security review, and verification loop

- Introduced coding standards for TypeScript and React in SKILL.md.
- Added continuous learning skill with configuration and evaluation scripts.
- Created detail layout guidelines for read-only pages.
- Established form layout rules for data-entry forms.
- Documented project guidelines for the frontend monorepo.
- Implemented security review checklist for frontend/Electron applications.
- Developed a verification loop skill for comprehensive session checks.

This commit enhances the skill set available for developers, ensuring adherence to best practices and improving code quality.

+## Available Agents
+
+| Agent                | Purpose                 | When to Use                   |
+| -------------------- | ----------------------- | ----------------------------- |
+| planner              | Implementation planning | Complex features, refactoring |
+| architect            | System design           | Architectural decisions       |
+| tdd-guide            | Test-driven development | New features, bug fixes       |
+| code-reviewer        | Code review             | After writing code            |
+| security-reviewer    | Security analysis       | Before commits                |
+| build-error-resolver | Fix build errors        | When build fails              |
+| e2e-runner           | Frontend journeys       | Vitest + RTL, browser flows   |
+| refactor-cleaner     | Dead code cleanup       | Code maintenance              |
+| doc-updater          | Documentation           | Updating docs                 |
+
+## Immediate Agent Usage
+
+No user prompt needed:
+
+1. Complex feature requests - Use **planner** agent
+2. Code just written/modified - Use **code-reviewer** agent
+3. Bug fix or new feature - Use **tdd-guide** agent
+4. Architectural decision - Use **architect** agent
+
+## Parallel Task Execution
+
+ALWAYS use parallel Task execution for independent operations:
+
+```markdown
+# GOOD: Parallel execution
+
+Launch 3 agents in parallel:
+
+1. Agent 1: Security analysis of auth.ts
+2. Agent 2: Performance review of cache system
+3. Agent 3: Type checking of utils.ts
+
+# BAD: Sequential when unnecessary
+
+First agent 1, then agent 2, then agent 3
+```
+
+## Multi-Perspective Analysis
+
+For complex problems, use split role sub-agents:
+
+- Factual reviewer
+- Senior engineer
+- Security expert
+- Consistency reviewer
+- Redundancy checker
