Perfdeck (formerly Perfmon): Consolidate CLI monitoring tools into a single TUI

Original post: https://news.ycombinator.com/item?id=47649701

Following some feedback about the original name being already taken, I have rebranded the project and released v0.3.0. This release isn't just a rename, it is s a complete refinement of the installation and cross-platform experience.

Homebrew is almost ready. Preparing for a Homebrew release (coming in v0.4.0).

I would love to hear your thoughts on the new name and the tabbed approach to monitoring.
