(new): add log level helpers and HTTP method levels

- move LogLevel and predefined levels into levels.go
- add level-specific constructors for info/warn/error/fatal/debug
- add predefined HTTP method log levels and LogLevelForMethod
- unify Logger Print/Println internals and add Printf
- improve GoDoc coverage for exported APIs

+# v2.2.0
+
+This release adds new public APIs for working with log levels, introduces HTTP method-specific log levels, and improves package documentation.
+
+### Added
+
+- Added dedicated log level constructors:
+  - `NewInfoLogLevel`
+  - `NewInfoLogLevelWithColors`
+  - `NewWarnLogLevel`
+  - `NewWarnLogLevelWithColors`
+  - `NewErrorLogLevel`
+  - `NewErrorLogLevelWithColors`
+  - `NewFatalLogLevel`
+  - `NewFatalLogLevelWithColors`
+  - `NewDebugLogLevel`
+  - `NewDebugLogLevelWithColors`
+- Added HTTP method-specific predefined log levels:
+  - `HTTPGetLevel`
+  - `HTTPHeadLevel`
+  - `HTTPPostLevel`
+  - `HTTPPutLevel`
+  - `HTTPPatchLevel`
+  - `HTTPDeleteLevel`
+  - `HTTPOptionsLevel`
+  - `HTTPConnectLevel`
+  - `HTTPTraceLevel`
+  - `HTTPUnknownLevel`
+- Added `LogLevelForMethod(method string) LogLevel` to map HTTP methods to predefined log levels.
+- Added `Logger.Printf(level, format, args...)` for formatted logging with an explicit log level.
+
+### Changed
+
+- Refactored log level definitions into a dedicated `levels.go` file.
+- Unified `Logger.Print` and `Logger.Println` through a shared internal implementation without changing their behavior.
+
+### Documentation
+
+- Improved GoDoc coverage for exported types, constructors, formatters, colors, HTTP helpers, and time layouts.
+- Expanded inline documentation for formatter tokens and default formatter behavior.
+
+### Compatibility
+
+- No breaking API changes.
+- Existing `Print`, `Println`, predefined levels, and color APIs remain compatible.
+
 # v2.1.0
 
 This release expands sneklog color customization while preserving compatibility with the v2.0.1 API.
