v2.43.0

Installation fixes:

• Fixed pyproject.toml missing deps (flask, flask-socketio, eventlet, psutil, textual, etc.)
• Updated requirements.txt to match pyproject.toml for pip users
• Added tmux to install-system-deps.sh and system-packages.txt
• Fixed setup_tools.sh Python path issue (added lib/ to sys.path)
• Updated minimum required settings section with correct variable names
• Added tools sync step (sync_tools.py) before bin/start in guide

Shell improvements:

• update-aliases.sh now auto-detects bash vs zsh (uses .bashrc or .zshrc)
• bin/jarvis-services --status flag to check actual daemon PIDs
• bin/start --list now checks PID files for services (not just tmux session)
• bin/start --stop now properly stops background daemon

Removed outdated migration plan documentation as the migration is complete.
