Source changelog

- Added new section outlining server-side rules that automatically modify posts (e.g., text length limits, media restrictions, hashtag caps, supported platforms/features). - Clarified content handling: platforms may cut off or reject content without an explicit error; guidance added to avoid unwanted data loss. - Documented unavailable features, such as Stories, polls, or analytics, to set accurate user expectations. - Removed the unused or redundant skill-card.md file for simplicity.
