Module logging 

Shared logging initialization for Robit binaries.

Provides a unified way to initialize logging with support for:

• Config file app.log_level setting
• Config file app.log_file setting (log to file, daily rotation)
• Environment variable RUST_LOG (takes precedence)
• Sensible defaults for third-party crates

Functions

init_logging

Initialize logging with optional app config and a target crate name.

init_logging_silent

Initialize logging but discard output (for TUI mode).
