v2.1.0

Matrix-themed development-environment automation. This release makes the language operators actually install their toolchains, adds observability tooling to the power-user operator, and lands a batch of dependency updates.

✨ Features

• Monitoring, git-stats & log tools for the jiveturkey operator — glances, duf, procs, git-quick-stats, lnav, grc, multitail, plus a monitor function that launches the best available dashboard (glances → btop → htop → top).

🐛 Fixes

• nodejs_dev and go_dev operators now install a real toolchain. They previously applied shell aliases/functions but installed zero tools — unregistered tools silently no-op'd through the install loop. Added per-ecosystem installers: nvm (Node.js + global npm CLIs) and go (toolchain + go install tools). Also fixed a broken nodeinfo command substitution and the renamed air module path.
• ls family (ls/ll/la/l/lt/l.) redefined as argument-forwarding shell functions, so flags like ls -al render a long listing instead of a grid.

🔧 Maintenance

• Python deps bumped: black, flake8, jinja2, pyyaml, setuptools-rust.
• GitHub Actions bumped: setup-python, upload-artifact, download-artifact, setup-buildx.
• First changelog managed by Commitizen (make bump).
