🚧 DeepNext status update

Reasoning (for context only)

The goal is to make INFO the default logging level and allow overriding it via the
LOG_LEVEL environment variable. The project uses Loguru for logging, and logging is
initialized in multiple entrypoints (apps/app/deep_next/app/entrypoint.py,
apps/app/deep_next/app/entrypoint_scheduled.py, libs/core/deep_next/core/entrypoint.py).
To ensure consistent behavior and avoid code duplication, a centralized logging setup
function should be implemented in a shared utility module
(libs/common/deep_next/common/common.py). This function will read the LOG_LEVEL
environment variable (defaulting to INFO), remove existing Loguru handlers, and add a
new handler with the correct level. All entrypoints should call this setup function
immediately after loading environment variables and before any logger usage. Adding a
LOG_LEVEL example to .env.example will help users discover and configure this option.
This approach is simple, maintainable, and aligns with project conventions.

Add some documentation to README

🚧 DeepNext status update

Reasoning (for context only)

The task is to make INFO the default logging level, allow overriding it via the
LOG_LEVEL environment variable, and—based on feedback—add documentation to the README.
The project uses Loguru for logging, and logging is initialized in multiple entrypoints.
To ensure consistent behavior and avoid code duplication, a centralized setup_logging()
function should be implemented in libs/common/deep_next/common/common.py. All
entrypoints should call this function after loading environment variables and before any
logger usage. The .env.example should include a commented LOG_LEVEL example for
discoverability. Finally, the README should be updated to document the LOG_LEVEL
variable and its effect, as requested in the feedback. This approach is simple,
maintainable, and aligns with project conventions.
