Implement comprehensive weather parsing capabilities following Clean
Architecture principles with composite parser pattern for routing between
aviation and weather messages.
## Features Added
- Weather report parsing (METAR, SPECI, TAF)
- Composite parser pattern for message routing
- Lenient parsing with warnings for unrecognized tokens
- Support for PROB and RMK sections in TAF
- Rich domain modeling with typed weather elements
## Architecture
**Domain Layer** (internal/domain/weather/):
- WeatherMessage interface with Metar and Taf implementations
- Weather elements: Wind, Visibility, Cloud, Temperature, Altimeter, Phenomenon
- Domain errors: ErrInvalidFormat, ErrMissingStation, ErrMissingTime
**Port Layer** (internal/port/weather_parser.go):
- WeatherParser interface with CanParse and Parse methods
**Adapter Layer** (internal/adapter/parser/weather/):
- WeatherParserImpl with classification and parsing logic
- Comprehensive regex patterns for weather elements
- METAR/SPECI parser with element extraction
- TAF parser with period handling (FM, TEMPO, BECMG, PROB)
- Helper functions for time parsing and unit conversions
**Composite Parser** (internal/adapter/parser/composite.go):
- Routes weather reports to weather parser
- Falls back to aviation parser for telegrams
- Converts WeatherMessage to ParsedTelegram format
## Integration
- Updated ProvideParser to create composite parser with weather parser
- Added weather parser to Wire DI configuration
- Updated processor_bench_test.go for weather parser integration
- Documentation added in docs/weather-parser.md
## Testing
- 29 comprehensive tests for weather parsing (all passing)
- Tests for classification, METAR, SPECI, TAF, and composite routing
- Benchmark compatibility maintained
## Fixes Applied
- TAF PROB parsing: Include PROB/RMK in special section detection
- Composite test: Updated to use properly formatted AFTN telegram
- Linter issues: Switch statement refactor, removed unused patterns
- Ineffective break statement fixed in TAF parser
## Coverage
~1,743 lines of new code with:
- Complete METAR/SPECI parsing
- TAF parsing with period support
- Lenient error handling with warnings
- Unit conversions and time utilities
