feat(logger): enhance logging configuration with minLevel and silent option

Browse Source 
- Added a new LogLevel "silent" to suppress logging output.
- Replaced the debug boolean flag in LoggerConfig with a minLevel property to specify the minimum log level.
- Updated shouldLog function to respect the new minLevel configuration.
- Modified parseDebugFlag to return appropriate LogLevel based on truthy values.
- Updated main.tsx to accommodate changes in logging configuration, including parsing minLevel from attributes and options.
- Deprecated the debug flag in favor of minLevel for better clarity and control over logging behavior.
