refactor: Simplify BLE protocol implementation and remove scope creep
Major cleanup of BLE interface implementation to focus on core identity-based tracking goal while removing unnecessary complexity added during troubleshooting. Key changes: - Remove unified dual-connection architecture (single-direction connections) - Remove Protocol v1 MAC-based compatibility fallbacks (~200 lines) - Simplify connection handshake (handle_peripheral_data: 173→54 lines) - Extract _compute_identity_hash() helper (DRY: 11 duplicates removed) - Add 60s timeout to identity wait loop (prevent hung threads) - Remove GATT characteristic descriptors (UUID 2901) - Remove DIAGNOSTIC logging statements (~15 occurrences) - Revert TX characteristic to 'notify' flag (better throughput) Net reduction: 249 lines removed (473 deletions, 224 additions) Maintains core functionality: - Identity characteristic for stable tracking (MAC rotation immunity) - Identity-based device naming (Protocol v2.1) - MAC sorting for connection direction (Protocol v2.2) - Identity-keyed fragmenters/reassemblers 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
