feat: complete Phase 2 & 3 - projman plugin with commands and agents

Implemented complete projman plugin foundation for sprint planning and
project management with Gitea and Wiki.js integration.

Phase 2: Commands (5 total)
- /sprint-plan: AI-guided planning with planner agent
- /sprint-start: Sprint execution with orchestrator agent
- /sprint-status: Quick progress check
- /sprint-close: Lessons learned capture
- /labels-sync: Label taxonomy synchronization

Phase 3: Agents (3 total)
- Planner: Thoughtful sprint planning, asks questions, searches lessons
- Orchestrator: Concise coordination, lean prompts, tracks progress
- Executor: Precise implementation, follows specs, applies lessons

Components:
- plugin.json: Valid manifest with 5 commands, 3 agents, 1 skill
- .mcp.json: MCP configuration for Gitea + Wiki.js servers
- Label taxonomy skill with dynamic 44-label system
- README.md: Complete usage guide (409 lines)
- CONFIGURATION.md: Step-by-step setup instructions
- Local test marketplace for validation

Features:
- Branch-aware security (development/staging/production)
- Dynamic label taxonomy (fetched from Gitea, never hardcoded)
- Lessons learned integration (search at start, capture at close)
- Hybrid configuration (system + project level)
- Security best practices (${CLAUDE_PLUGIN_ROOT}, path safety)

Total: 13 plugin files, ~3,719 lines of documentation

Testing: docs/TEST_01_PROJMAN.md provides comprehensive testing plan

Ready for Phase 5: Testing & Validation
