docs: Enhance target_files documentation and fix cross-platform command compatibility

## Target Files Enhancement
- Add support for new file creation in target_files format
- Update task-generate.md with comprehensive target_files generation guide
- Update concept-enhanced.md to output code modification targets
- Add examples showing both modification (file:function:lines) and creation (file) formats

## Cross-Platform Command Fixes
- Replace ls with find commands for better Windows Git Bash compatibility
- Update workflow commands: execute.md, status.md, review.md
- Update session commands: list.md, complete.md
- Add Bash environment guidelines to context-search-strategy.md
- Document forbidden Windows commands (findstr, dir, where, etc.)

## Files Updated
- Core workflows: workflow-architecture.md, task-core.md
- Command docs: 9 workflow command files
- Agent docs: action-planning-agent.md, task-generate-agent.md
- Strategy docs: context-search-strategy.md

+**Purpose**: Identify specific code locations for modification AND new files to create

+**Source Data Priority**:
+1. **ANALYSIS_RESULTS.md** - Should contain identified code locations
+2. **Gemini/MCP Analysis** - From `analyze_task_patterns` step
+3. **Context Package** - File references from `focus_paths`
+
+**Format**: `["file:function:lines"]` or `["file"]` (for new files)
+- `file`: Relative path from project root (e.g., `src/auth/AuthService.ts`)
+- `function`: Function/method name to modify (e.g., `login`, `validateToken`) - **omit for new files**
+- `lines`: Approximate line range (e.g., `45-52`, `120-135`) - **omit for new files**
+
+**Examples**:
+```json
+"target_files": [
+  "src/auth/AuthService.ts:login:45-52",
+  "src/middleware/auth.ts:validateToken:30-45",
+  "src/auth/PasswordReset.ts",
+  "tests/auth/PasswordReset.test.ts",
+  "tests/auth.test.ts:testLogin:15-20"
+]
+```
+
+**Generation Strategy**:
+- **New files to create** → Use `["path/to/NewFile.ts"]` (no function or lines)
+- **Existing files with specific locations** → Use `["file:function:lines"]`
+- **Existing files with function only** → Search lines using MCP/grep `["file:function:*"]`
+- **Existing files (explore entire)** → Mark as `["file.ts:*:*"]`
+- **No specific targets** → Leave empty `[]` (agent explores focus_paths)
