Add Pesty to Clipboard Managers

[momenbasel]

What

Adds Pesty to the Clipboard Managers section.

- [Pesty](https://github.com/momenbasel/pesty) - Native open source clipboard manager with pinboards and instant search. ![Open Source][oss]

Placed alphabetically between Maccy and Yippy.

Why it fits

Pesty is a free, MIT-licensed, native SwiftUI clipboard manager for macOS — squarely in scope for this section alongside Maccy and Yippy (both ![Open Source][oss]).

• Open source (MIT) — full source at https://github.com/momenbasel/pesty, so the ![Open Source][oss] badge applies, matching the neighboring entries.
• Native, zero dependencies — pure SwiftUI, universal binary (Apple Silicon + Intel), Developer ID signed and Apple-notarized.
• Features — slide-up, color-coded clipboard strip, pinboards, instant search, and fully keyboard-driven pasting.
• Easy install — brew install --cask momenbasel/pesty/pesty. Also available on the Mac App Store (paid) for users who prefer it, but the app itself is open source and free to build/run.
• Homepage — https://www.moamenbasel.com/pesty/

Format compliance

• Single-line entry, sentence-case description ending in a period before the badge.
• Uses the existing [oss] badge reference; no new assets or link definitions added.
• Inserted in alphabetical order within the section.
