fix: allow read-only CALL db.* Cypher queries + fix egg-info exclusion

McpTools run_cypher:
- \bCALL\b blocked ALL Cypher CALL statements including read-only
  fulltext search (CALL db.index.fulltext.queryNodes)
- Changed to \bCALL\s+(?!db\.)\b — blocks mutation procedures
  while allowing CALL db.* (indexes, schema, fulltext search)

FileDiscovery:
- "*.egg-info" in DEFAULT_EXCLUDES never matched because
  Set.contains() does exact match, not glob. Real dirs are named
  like "mypackage.egg-info"
- Removed glob from set, added suffix match in isExcluded()
