Added a new method to the AirtimeManager class to refresh modulation parameters without clearing transmission history. Updated ConfigManager to call this method after applying live radio configurations. Enhanced tests to verify that modulation updates occur correctly during live updates.
AirtimeManager.calculate_airtime now uses openhop_core's
calculate_lora_airtime_ms, which matches RadioLib's getTimeOnAir. This
adopts the radio driver's symbol-time auto-LDRO rule in place of the
SF/BW shorthand, which diverged from hardware at 16.384 ms symbol
settings such as SF12 @ 250 kHz and SF10 @ 62.5 kHz. Test oracles
follow the same rule, with literal RadioLib-derived regression values
for the divergent settings.
AirtimeManager fed the configured coding rate straight into the Semtech
symbol formula, so a config using the legacy index form (1..4) would
multiply payload symbols by the raw index instead of the 4/5..4/8
denominator and undercount airtime. Normalize through openhop_core's
shared coding_rate_denominator() before calculating.
- Updated byte representations in tests to use lowercase hex format for consistency.
- Reformatted code for better readability, including line breaks and indentation adjustments.
- Consolidated multiple lines into single lines where appropriate to enhance clarity.
- Ensured that all test cases maintain consistent formatting and style across the test suite.
- Introduced `total_rx_airtime_ms` in `AirtimeManager` to track received packet airtime.
- Added `record_rx` method to log received airtime in `AirtimeManager`.
- Updated `RepeaterHandler` to count received packets and log RX airtime using the new method.
- Enhanced statistics reporting in `get_stats` to include total received airtime.
- Updated `ProtocolRequestHelper` to include total RX airtime in the RepeaterStats structure for better monitoring.
- Introduce GPIO chip selection and GPIO backend selection
- Add default Femtofox settings (for SX1262 as LR1121 support may come later)
- Add support for Python 3.10 UTC to reduce footprint
- Fix airtime calculation bandwidth variable naming
- Add service auto-enable when starting
- Add Australia: SA, WA, QLD radio preset
- Add Snyk security instructions

Based on PR #69
Replace simplified airtime calculation with the proper Semtech reference
formula that accounts for:
- Coding rate (CR)
- CRC overhead
- Explicit/implicit header mode
- Low data rate optimization (SF11/SF12 at 125kHz)
The previous formula significantly underestimated airtime, especially
at higher spreading factors, leading to inaccurate duty cycle tracking.

This commit sets up the initial project structure for the PyMC Repeater Daemon.
It includes base configuration files, dependency definitions, and scaffolding
for the main daemon service responsible for handling PyMC repeating operations.
