copilot-swe-agent[bot] 2a5a1acd62 Fix runtime errors and improve robustness in host configs and scripts
- Fix KeyError in julia.nix when Project.toml lacks deps table
- Fix incorrect uv args in python.nix (remove --run + --add-flags combination)
- Remove redundant 'uv add ipython' from sync branch in python.nix
- Fix relative paths in project-scripts.nix (./scripts -> ../scripts)
- Fix initProject.sh to check file existence before git add
- Add RVER validation in updateDeps.sh with proper error handling
- Add tool availability checks in updateDeps.sh (uv, julia, devenv)
- Add flake.nix backup before modification in updateDeps.sh
- Ensure updateDeps.sh runs from repository root

# Python-related host configurations
#
# This module defines all Python-related commands available in the dev shell.
# Each command is configured with enable conditions and execution paths.
#
# Available commands (when Python is enabled):
# - <name>-marimo: Launch Marimo notebook (interactive Python notebooks)
# - <name>-py: Run Python interpreter
# - <name>-ipy: Launch IPython REPL (enhanced interactive shell)
# - <name>-initPython: Initialize Python project with uv
#
# How it works:
# - Commands are enabled based on config.enabledLanguages.python
# - UV (Python package manager) handles project dependencies
# - Each command auto-initializes project if pyproject.toml doesn't exist
#
# Dependencies: uv, python, nodejs, basedpyright (configured in flake.nix)
