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: Run tests with coverage or generate tests for specified code
+---
+
+# Test
+
+## Skills Required
+
+- skills/test-standards.md
+
+## Purpose
+
+Unified testing command for running tests and generating new tests.
+
+## Invocation
+
+```
+/test                       # Default: run tests
+/test run                   # Run tests, check coverage
+/test run --coverage        # Run with coverage report
+/test run --verbose         # Verbose output
+/test gen <target>          # Generate tests for target
+/test gen <target> --type=unit      # Specific test type
+/test gen <target> --framework=jest # Specific framework
+```
+
+## Mode Selection
+
+- No args or `run` → **Run Mode**
+- `gen <target>` → **Generate Mode**
+
+---
+
+## Mode: Run
+
+Run tests and verify coverage before sprint close.
+
+### Workflow
+
+1. **Detect Framework**
+   Check for: pytest.ini, package.json, go.mod, Cargo.toml, etc.
+
+2. **Run Tests**
+   Execute appropriate test command for detected framework.
+
+3. **Check Coverage** (if --coverage or available)
+   Report coverage percentage.
+
+4. **Sprint File Analysis**
+   Identify sprint files without tests.
+
+See `skills/test-standards.md` for framework detection and commands.
+
+### DO NOT (Run Mode)
+
+- Modify test files
+- Skip failing tests to make run pass
+- Run tests in production environments
+- Install dependencies without asking
+
+---
+
+## Mode: Generate
+
+Generate comprehensive tests for specified code.
+
+### Arguments
+
+- **Target:** File path, function name, class name, or module
+- **--type:** unit (default), integration, e2e, snapshot
+- **--framework:** Auto-detected or specified (pytest, jest, vitest, go test)
+
+### Workflow
+
+1. **Analyze Target Code**
+   Parse signatures, identify dependencies, map types.
+
+2. **Determine Test Strategy**
+   Based on code pattern:
+   - Pure function → unit tests with multiple inputs
+   - Class → instance lifecycle tests
+   - API endpoint → request/response tests
+   - Component → render and interaction tests
+
+3. **Generate Tests**
+   - Happy path cases
+   - Edge cases (empty, null, boundary)
+   - Error cases (invalid input, exceptions)
+   - Type variations (if applicable)
+
+4. **Output File**
+   Create test file with proper structure and naming.
+
+See `skills/test-standards.md` for test patterns and structure.
