Centralized logging configuration for Open Sesame

Ensures all tracing output goes to stderr (never stdout) to prevent corruption of user-facing output during stdout redirection.

§Critical Design Requirements

All logs MUST go to stderr: This is enforced by .with_writer(std::io::stderr) on all tracing_subscriber::fmt() calls. This ensures commands like sesame --print-config > config.toml produce clean output files.
Centralized configuration: All logging setup is in this single module to prevent future developers from accidentally creating stdout loggers.
Three logging modes:
- Default: SILENT (no logging at all)
- With RUST_LOG env: file logging at specified level
- With debug-logging feature: file logging at DEBUG level

use open_sesame::util::log;

log::init();
tracing::info!("Application started");
