Major refactor of how we handle the CLI with socials, added more platform support, fixed CLI -> image count disparity, updated README to reflect changes

This PR covers issues #14, #18, #25, partial coverage of #29, and #32

Overview

Refactored Pixel Forge to focus on OpenGraph website sharing. Fixed broken CLI platform flags, added 6 new platforms, and simplified generators to produce 1-2 images per platform instead of multiple content formats.

Key Changes

Architecture:

• Created BaseOpenGraphGenerator for consistent platform generation
• Focused all generators on OpenGraph (removed Stories, Reels, vertical videos)
• Standardized 1200x630 format across social platforms

Platform Support:

• Added Discord, Telegram, Signal, Slack, Threads, Snapchat generators
• Fixed broken individual platform flags (--discord, --telegram, etc.)
• Enhanced --social flag: 11 platforms, 14 files

CLI Fixes:

• Removed "My App" text overlay on generated images
• Fixed TypeScript conflicts in TwitterGenerator
• All platform flags now functional

Documentation:

• Reorganized README with flag-based platform matrices
• Updated examples to match actual output

Breaking Changes

Platform	Before	After
Instagram	5 files (Square, Portrait, Stories, Reels, Landscape)	1 file (instagram.png)
TikTok	2 files (Vertical + Profile)	1 file (tiktok.png)
Snapchat	1 file (1920x1080)	1 file (snapchat.png 1200x630)

New generators: Discord, Telegram, Signal, Slack, Threads, Snapchat - all generate single 1200x630 OpenGraph images.

Files Changed

New (10): Base architecture + 6 platform generators + 3 format generators
Modified (6): CLI, Instagram/TikTok/Twitter generators, comprehensive generator, exports, README

Impact

Production-ready OpenGraph generator with 11 working platforms, consistent output, and extensible architecture for future platforms.
