[Swift] Canonicalize LogLevel to debug/warn/error/none

[markmur]

What

Canonicalizes LogLevel to an ordered, threshold-based set: debug, warn, error, none.

• debug is the most verbose; none silences everything.
• Selecting a level emits that level and every more-severe level.
• Drops the old .all case (breaking) and adds .warn plus OSLogger.warn(_:).
• Default is now .warn (was .error), aligning Swift with the other platforms.

Previously the filter matched the level exactly, so .debug silenced errors and faults. The ordered comparison fixes that.

Threshold

logLevel	debug	warn	error
.debug	✅	✅	✅
.warn (default)	–	✅	✅
.error	–	–	✅
.none	–	–	–

Usage

var configuration = Configuration()

configuration.logLevel = .debug   // debug + warnings + errors
configuration.logLevel = .warn    // warnings + errors (default)
configuration.logLevel = .error   // errors only
configuration.logLevel = .none    // silence everything
