Add initial implementation framework for Ruuvi Air support:

## Parser Library Integration
- Add Ruuvi Air Format 6 parser to ruuvitag-common-java dependency
- Configure BND embedding to include parser library in bindings

## Bluetooth Binding Foundation
- Add air quality channel constants to RuuviTagBindingConstants
- Extend RuuviTagHandler with Format 6 measurement handling
- Define thing-type and channel-type stubs for Ruuvi Air in XML

## MQTT Binding Foundation
- Add air quality channel constants to RuuviGatewayBindingConstants
- Extend RuuviTagHandler with Format 6 measurement handling
- Define thing-type and channel-type stubs for Ruuvi Air in XML

## Documentation
- Create IMPLEMENTATION_SUMMARY.md with implementation overview
- Update PLAN.md with detailed implementation progress

This commit provides the foundational structure for full Ruuvi Air support.

…r channel types

Implement complete Ruuvi Air Format 6 support across Bluetooth and MQTT bindings:

## Architecture Changes
- Separate RuuviTag and Ruuvi Air into distinct thing-types in both bindings
- Define shared channel-types (temperature, humidity, pressure, dataFormat) used by both devices
- Rename calibrationStatus to calibrationCompleted with Switch item type semantics

## Bluetooth Binding
- Rename ruuvitag.xml to ruuvi.xml to reflect support for both device types
- Add ruuviair_beacon thing-type with air quality specific channels
- Create separate RuuviTag-specific channels (acceleration, battery, txPower, movementCounter)
- Remove unused StringType updateStateIfLinked method
- Update RuuviTagBindingConstants with THING_TYPE_AIR_BEACON
- Update RuuviTagHandlerFactory to support both thing-types

## MQTT Binding
- Add ruuviair_beacon thing-type to thing-types.xml
- Create RuuviCachedSwitchState class for proper Switch channel state caching
- Update handler to use new RuuviCachedSwitchState for calibrationCompleted channel
- Update RuuviGatewayBindingConstants with THING_TYPE_AIR_BEACON
- Add tags to ruuvitag_txPower for consistency with Bluetooth binding

## Air Quality Channels (Ruuvi Air only)
- pm25: Particulate matter ≤2.5 μm concentration
- co2: CO2 concentration in ppm
- vocIndex: Volatile Organic Compounds index (0-500, avg=100)
- noxIndex: Nitrogen Oxides index (0-500, base=1)
- luminosity: Light intensity in lux
- calibrationCompleted: Sensor calibration status (ON=complete, OFF=in progress)

## Documentation
- Update both binding READMEs with comprehensive channel tables
- Document supported devices: RuuviTag (all variants) and Ruuvi Air
- Add air quality index interpretation section explaining VOC and NOX semantics
- Ensure channel description consistency across both bindings

Both RuuviTag and Ruuvi Air devices are now handled by the same
handler class, so RuuviHandler is a more appropriate name than
RuuviTagHandler to reflect its broader responsibility.

Add missing case statements for PM1, PM4, and PM10 particulate matter
channels in MQTT Ruuvi Gateway binding handler.

Add airQualityIndex channel to both Bluetooth RuuviTag and MQTT RuuviGateway
bindings. This calculated index (0-100%) combines PM2.5 and CO2 values to
provide a comprehensive air quality assessment for Ruuvi Air devices.

- Update channel definitions with airQualityIndex
- Add handler implementations for both BLE and MQTT bindings
- Update README documentation with examples
- Fixed 0-100% description in XML definitions
