Title:
Fix system screenshots missing & add support for PNG/JPG formats

Description:

Summary

This PR restores the missing system screenshot monitoring functionality and significantly improves image clipboard support for modern applications (e.g., WeChat, Lark/Feishu, Web Browsers). It also resolves stability issues caused by overly aggressive clipboard polling.

Key Changes

1. Restore System Screenshot Monitoring

Re-implemented ScreenShotObserverDelegate in AppDelegate.swift.
Replaced the removed RxScreeen dependency with a native delegate implementation, ensuring system screenshots (Cmd+Shift+3/4) are automatically detected and saved to history.

2. Enhanced Image Format Support

Added native support for public.png, public.jpeg, and public.tiff pasteboard types.
Problem: Previously, Clipy relied on the deprecated NSTIFFPboardType. This caused it to ignore images copied from apps that write modern standard formats (like Chrome "Copy Image" or IM apps).
Solution: Updated CPYClipData, MenuManager, and ClipService to recognize these types as valid images and generate thumbnails/titles correctly.

3. Stability & Performance Improvements

Fix Polling Interval: Corrected ClipService polling interval from 750 microseconds to 750 milliseconds.
- Impact: The previous microsecond interval was too aggressive, causing race conditions where Clipy would try to read the clipboard before the writing app finished, resulting in "hit or miss" capture behavior.
Improved Deduplication: Updated CPYClipData.hash to include image dimensions (width ^ height).
- Impact: Prevents different images that happen to have similar data sizes from being incorrectly treated as duplicates and discarded.
Robust Thumbnail Generation: Updated NSImage+Resize.swift to add a fallback drawing mechanism when NSBitmapImageRep is nil, ensuring thumbnails are generated for all image types.

Verification

System screenshots are now automatically saved to history.
Images copied from (PNG/JPG) are correctly saved and displayed.
Fixed stability issues where clipboard updates were sometimes missed.
Thumbnails are correctly generated for all supported image types.

i don't think this project is actively managed, we can start separate fork if we found couple of active contributer @pokocat
