refactor(hooks): rename ultrawork-mode to keyword-detector with multi-keyword support

- Detect ultrawork, search, analyze keywords (EN/KO/JP/CN/VN)
- Add session-based injection tracking (once per session)
- Remove unnecessary state management

+## AGENT UTILIZATION PRINCIPLES (by capability, not by name)
+- **Codebase Exploration**: Spawn exploration agents using BACKGROUND TASKS for file patterns, internal implementations, project structure
+- **Documentation & References**: Use librarian-type agents via BACKGROUND TASKS for API references, examples, external library docs
+- **Planning & Strategy**: NEVER plan yourself - ALWAYS spawn a dedicated planning agent for work breakdown
+- **High-IQ Reasoning**: Leverage specialized agents for architecture decisions, code review, strategic planning
+- **Frontend/UI Tasks**: Delegate to UI-specialized agents for design and implementation
+
+## EXECUTION RULES
+- **TODO**: Track EVERY step. Mark complete IMMEDIATELY after each.
+- **PARALLEL**: Fire independent agent calls simultaneously via background_task - NEVER wait sequentially.
+- **BACKGROUND FIRST**: Use background_task for exploration/research agents (10+ concurrent if needed).
+- **VERIFY**: Re-read request after completion. Check ALL requirements met before reporting done.
+- **DELEGATE**: Don't do everything yourself - orchestrate specialized agents for their strengths.
+
+## WORKFLOW
+1. Analyze the request and identify required capabilities
+2. Spawn exploration/librarian agents via background_task in PARALLEL (10+ if needed)
+3. Use planning agents to create detailed work breakdown
+4. Execute with continuous verification against original requirements
