improve CLI with auto project name and .gitignore support

- Make index_name optional, auto-use current directory name
- Read .gitignore patterns and respect them during indexing
- Add _read_gitignore_patterns() to parse .gitignore files
- Add _should_exclude_file() for pattern matching
- Apply exclusion patterns to both PDF and general file processing
- Show helpful messages about gitignore usage

Now users can simply run: leann build
And it will use project name + respect .gitignore patterns.
