feat: implement application management system

Add structured workflow for managing job applications with /new-application and /populate-application commands. Users can now organize applications in dated folders, store job documents, and have AI analyze requirements to populate strategy documents. Includes bug fix for src/ path references and safe update documentation.

+# Updating the Test Framework
+
+## ⚠️ CRITICAL: Preserve User Data During Updates
+
+When updating the test framework at `~/workspace/test-bewerbungen/`, you MUST preserve user data files. **NEVER** use `cp -r src/* ~/workspace/test-bewerbungen/` as this overwrites everything including user work.
+
+## Protected Files & Folders
+
+**NEVER overwrite these in the test directory:**
+- `profile.md` - Contains user's personal and professional information
+- `applications/` folder - Contains all job application work in progress
+- Any PDF files - User's CVs, certificates, or job-related documents
+- Any user-created files or modifications
+
+## Safe Update Process
+
+### Method 1: Selective File Update (Recommended)
+
+Update only framework code files, preserving user data:
+
+```bash
+# Update main instruction file
+cp src/CLAUDE.md ~/workspace/test-bewerbungen/
+
+# Update slash commands and templates
+cp -r src/.claude ~/workspace/test-bewerbungen/
+
+# ONLY create applications directory if it doesn't exist
+# (don't overwrite existing one with user's applications)
+if [ ! -d ~/workspace/test-bewerbungen/applications ]; then
+  mkdir -p ~/workspace/test-bewerbungen/applications/pending
+fi
+```
+
+### Method 2: Manual Selective Copy
+
+For more control, copy specific files individually:
+
+```bash
+# Framework instructions
+cp src/CLAUDE.md ~/workspace/test-bewerbungen/
+
+# Slash commands
+cp src/.claude/commands/new-application.md ~/workspace/test-bewerbungen/.claude/commands/
+cp src/.claude/commands/populate-application.md ~/workspace/test-bewerbungen/.claude/commands/
+cp src/.claude/commands/validate-profile.md ~/workspace/test-bewerbungen/.claude/commands/
+
+# Templates
+cp src/.claude/templates/application-template.md ~/workspace/test-bewerbungen/.claude/templates/
+```
+
+### ❌ NEVER Use These Commands on Test Directory
+
+```bash
+# DANGEROUS - Overwrites everything including user data
+cp -r src/* ~/workspace/test-bewerbungen/
+
+# DANGEROUS - Overwrites user's profile
+cp src/profile.md ~/workspace/test-bewerbungen/
+
+# DANGEROUS - Deletes user's applications
+rm -rf ~/workspace/test-bewerbungen/applications/
+```
+
+## When to Update Test Framework
+
+Update the test directory when:
+- Adding new slash commands to `src/.claude/commands/`
+- Modifying the application template in `src/.claude/templates/`
+- Updating framework instructions in `src/CLAUDE.md`
+- Fixing bugs in command logic
+
+**Do NOT update** `profile.md` or touch the `applications/` folder - these belong to the user.
+
+## Workflow Summary
+
+1. **Make changes** to framework files in `src/`
+2. **Test locally** in development environment first
+3. **Selectively copy** only framework files to test directory
+4. **Verify** user data (`profile.md`, `applications/`) remains intact
+5. **Test** the updated commands in the test environment
+

+
+**Remember**: The test directory simulates a real user's environment. Treat user data with care!
