refactor(projman): extract skills and consolidate commands

Major refactoring of projman plugin architecture:

Skills Extraction (17 new files):
- Extracted reusable knowledge from commands and agents into skills/
- branch-security, dependency-management, git-workflow, input-detection
- issue-conventions, lessons-learned, mcp-tools-reference, planning-workflow
- progress-tracking, repo-validation, review-checklist, runaway-detection
- setup-workflows, sprint-approval, task-sizing, test-standards, wiki-conventions

Command Consolidation (17 → 12 commands):
- /setup: consolidates initial-setup, project-init, project-sync (--full/--quick/--sync)
- /debug: consolidates debug-report, debug-review (report/review modes)
- /test: consolidates test-check, test-gen (run/gen modes)
- /sprint-status: absorbs sprint-diagram via --diagram flag

Architecture Cleanup:
- Remove plugin-level mcp-servers/ symlinks (6 plugins)
- Remove plugin README.md files (12 files, ~2000 lines)
- Update all documentation to reflect new command structure
- Fix documentation drift in CONFIGURATION.md, COMMANDS-CHEATSHEET.md

Commands are now thin dispatchers (~20-50 lines) that reference skills.
Agents reference skills for domain knowledge instead of inline content.

+description: Complete reference of available Gitea MCP tools with usage patterns
+---
+
+# MCP Tools Reference
+
+## Purpose
+
+Provides the complete reference of available MCP tools for Gitea operations. This skill ensures consistent tool usage across all commands and agents.
+
+## When to Use
+
+- **All agents**: When performing any Gitea operation
+- **All commands**: That interact with issues, labels, milestones, wiki, or dependencies
+
+## Critical Rules
+
+### NEVER Use CLI Tools
+
+**FORBIDDEN - Do not use:**
+```bash
+tea issue list
+tea issue create
+tea pr create
+gh issue list
+gh pr create
+curl -X POST "https://gitea.../api/..."
+```
+
+**If you find yourself about to run a bash command for Gitea, STOP and use the MCP tool instead.**
+
+### Required Parameter Format
+
+All tools require the `repo` parameter in `owner/repo` format:
+```python
+# CORRECT
+get_labels(repo="org/repo")
+list_issues(repo="org/repo", state="open")
+
+# INCORRECT - Will fail!
+get_labels()  # Missing repo parameter
+```
