FIX(app): add projects path to prompt

Updated orchestrator prompt to include:
- Explicit /app/projects/ path information
- List of available repositories (11 repos)
- Instruction to use /app/projects when user asks about Projects folder
- Added git_read_file and git_show_file_changes to tool documentation

This fixes the issue where orchestrator tried to access 'Projects' instead of '/app/projects'.
