b72690d954 feat: add Neo4j backend and refactor file graph architecture
- add neo4j dependency to project requirements
- introduce NetworkXFileGraph to replace LocalFileGraph implementation
- rename local_file_graph.py to networkx_file_graph.py with updated
  component registration as 'networkx'
- remove pickle persistence logic from NetworkX backend, simplify
  initialization
- update Neo4jFileGraph to return FileLink objects instead of
  (FileNode, FileLink) tuples from get_inlinks/get_outlinks methods
- remove unused AsyncIterator import and adjust method signatures
- add BareFileParser for handling binary/attachment files without
  content parsing
- move wikilink resolution utilities to dedicated utility module
- refactor memory I/O to use file graph's link resolution methods
  directly
- remove link extraction utilities from schema module, consolidate
  in utils.wikilink_resolver
