Replace native HTML title attributes on help icons with the
existing RichTooltip component for consistent cross-browser
tooltip behavior. The native title attribute has inconsistent
behavior across Safari and Edge, causing help tooltips to not
appear when users interact with the question mark icons.
Fixes#538
This PR provides full cross-platform support (Windows/macOS/Linux) for the development environment.
Key Changes
Makefile: Refactored dev and stop targets using cross-env and kill-port to support PowerShell/CMD.
Compatibility: Replaced Unix-specific grep/awk in the help target with a Python one-liner.
Bug Fix: Added encoding='utf-8' to tools/sync_vuegraphs.py to prevent charmap decode errors on Windows systems.
Dependencies: Added necessary dev-tools to package.json files to ensure a seamless "clone and run" experience.
