Summary: ChatDOC adds cross-page table analysis support

Why It Matters: Analyzing data that spans multiple pages is a common pain point for researchers and financial analysts. This update suggests the tool can now handle complex document structures better than before.

What Changed:

• Added "Cross-Page Table" as a featured capability on the homepage.
• Replaced the generic "Image" feature highlight with this specific table analysis feature.
• Updated the supported file types list to explicitly include MD and TXT formats in more sections.
