Bug Fixes

Module Loading & Migrations

• Fix critical timing issue where plugin setup functions ran before database migrations completed
• Implement two-phase module loading: first discover models → run migrations → execute setup functions

Redis Startup

• Disable Redis by default (REDIS_ENABLED=False) to prevent 5-second startup delay
• Reduce Redis connection timeout from 5s to 2s for faster failure detection
• Change Redis unavailable log level from error to debug for cleaner output

CLI & Server

• Fix CLI start server command for production mode
• Fix start server path resolution
• Remove DevBackboneContext from CLI scaffold (simplified context factory)
• Add get_db() async function to context factory for Depends usage

Model Discovery

• Fix relative import resolution by loading sibling files before __init__.py

Performance

Environment Validation

• Optimize env_validator to use pre-loaded constants instead of repeated decouple_config() calls
• Eliminates disk I/O during startup validation

Startup Time

• Remove backbone test execution from server startup (was blocking initialization)

Configuration Changes

Removed

• DEVELOPMENT_MODE environment variable (use CLI --dev flag instead)
