refactor(strategy): extract auto-tune core logic into pwnagotchi/strategy module

Browse Source 
Extracted intelligent channel selection strategy from auto-tune plugin into core
as pwnagotchi/strategy/ module with 3 focused components:

1. channels.py: ChannelStrategy
   - Selects channels for each epoch (active + extra unscanned)
   - Builds on active_channels and explores new areas
   - Handles channel list repopulation from config/agent

2. statistics.py: ChannelStatistics
   - Tracks per-channel statistics (AP counts, interactions)
   - Maintains known AP database
   - Manages active vs unscanned channel lists
   - Records interactions (assoc, deauth, handshakes)

3. __init__.py: Strategy facade
   - Unified entry point for agent integration
   - Event handler dispatch
   - Public API for stats access

Key changes:
- Strategy is now ALWAYS active (not optional like plugin)
- Personality/config loaded from config.toml, not plugin options
- No web UI or preset management (core only)
- Clean event integration with agent
- Removed ~600 lines of UI/preset code

Auto-tune.py is now DISABLED. Original backed up as auto-tune.py.backup.

The strategy replaces the removed RL-based AI with intelligent heuristics:
- Always scan active channels (high capture probability)
- Explore unscanned channels (discovery)
- Track statistics to guide behavior
- Adapt to environment changes

Configuration in config.toml:
    [main]
    extra_channels = 15
    restrict_channels = [1, 6, 11]  # optional
