docs: reorganize README to highlight file/directory capabilities

- Add key capability highlight in the intro about reading files/directories
- Move File & Directory Support section up before Quickstart
- Remove duplicate Directory Support Features section from tool parameters
- Make the file handling capability more prominent as it's a core feature

This better communicates the server's primary strength of passing entire
codebases to Gemini for comprehensive analysis.

+## File & Directory Support

+All tools accept both individual files and entire directories. The server:
+- **Automatically expands directories** to find all code files recursively
+- **Intelligently filters** hidden files, caches, and non-code files
+- **Handles mixed inputs** like `"analyze main.py, src/, and tests/"`
+- **Manages token limits** by loading as many files as possible within Gemini's context

-### Directory Support Features
-
-- **Automatic Expansion**: Directories are recursively scanned for code files
-- **Smart Filtering**: Hidden files, caches, and non-code files are automatically excluded
-- **Token Management**: Loads as many files as possible within token limits
-- **Clear Markers**: Each file is marked with full path for Gemini to distinguish

-Example with mixed paths:
-```
-"Use gemini to analyze config.py, src/, and tests/unit/ to understand the testing strategy"
