Removes the zep-cloud dependency entirely and replaces it with a
local file-based graph store (LocalGraphStore) that persists nodes,
edges, and episodes as JSON files under uploads/graphs/{graph_id}/.
- Add backend/app/utils/local_graph_store.py: thread-safe JSON store
with keyword search, node upsert, and episode append
- Rewrite graph_builder.py: LLM-based entity/relationship extraction
from text batches, stored locally instead of sent to Zep Cloud
- Rewrite zep_graph_memory_updater.py: agent activities written as
episodes + searchable fact edges in local JSON
- Rewrite zep_entity_reader.py: reads nodes/edges from local JSON
- Rewrite zep_tools.py: keyword search on local JSON replaces
Zep semantic search; _local_search is now the primary path
- Update oasis_profile_generator.py: local store replaces Zep client
for entity context enrichment
- Update ontology_generator.py: generated code template uses
pydantic BaseModel instead of Zep EntityModel/EdgeModel
- Convert zep_paging.py to a no-op stub (pagination not needed)
- Remove ZEP_API_KEY from config.py, add GRAPH_STORAGE_DIR
- Remove ZEP_API_KEY guards from api/graph.py and api/simulation.py
- Remove zep-cloud==3.13.0 from requirements.txt and pyproject.toml

Background threads (graph building, simulation prep, report generation,
profile generation) now inherit the requesting user's locale preference.
Previously these fell back to 'zh' because Flask request context was
unavailable in spawned threads.
- Updated README.md to include new simulation scripts and configuration details for OASIS, including API retry mechanisms and environment variable settings.
- Added simulation management and configuration generation services to streamline the simulation process across Twitter and Reddit platforms.
- Introduced new API routes for simulation-related operations, including entity retrieval and simulation status management.
- Implemented a robust retry mechanism for external API calls to improve system stability.
- Enhanced task management model to include detailed progress tracking.
- Added logging capabilities for action tracking during simulations.
- Included new scripts for running parallel simulations and testing profile formats.
- Updated `run.py` to conditionally print startup information only in the reloader process to avoid duplicate logs in debug mode.
- Modified `__init__.py` to log startup and completion messages based on the reloader process condition.
- Added warnings suppression in `graph_builder.py` for Pydantic v2 regarding Field usage.
- Revised `ontology_generator.py` to enforce strict design guidelines for entity types and relationships, ensuring compliance with new requirements.
- Improved logging behavior in `logger.py` to prevent log propagation to the root logger, avoiding duplicate outputs.
