Add pi3b hardware tier and resource guards for condo Pi deployment
...
- Add pi3b tier (700MB RAM limit, 8 passive/2 active modules, no bettercap/mitmproxy)
- Update detect_hardware_tier() to detect Raspberry Pi 3B by model string and BCM2837
- Add pi3b section to hardware_tiers.yaml
- Add systemd MemoryMax/CPUQuota/OOMScoreAdj to all three service files
- Fix bigbrother-watchdog.service ExecStart (was calling non-existent ResourceMonitor().run())
- Add scripts/run_watchdog.py as standalone health monitor daemon

Add Phase 1 core infrastructure: event bus, state manager, engine, capture bus, tool manager, scheduler, resource monitor, kill switch
...
Core framework (8 files in core/) + BaseModule ABC (2 files in modules/):
- bus.py: Multiprocess-safe pub/sub event bus using mp.Queue with background dispatcher thread, 20 canonical event types
- state.py: SQLite persistent state with WAL mode, dedicated writer thread with 500ms coalesce, module status + generic key-value store
- engine.py: Module lifecycle manager with multiprocess model, dependency resolution (topological sort), hardware tier detection (opi_zero3/pi_zero/generic), resource budgeting, scope enforcement, engagement phase gating
- capture_bus.py: Single AF_PACKET socket packet demux with per-module subscriber queues, BPF filter matching, drop-oldest backpressure
- tool_manager.py: Subprocess lifecycle for external tools (bettercap/tcpdump/Responder/mitmproxy/ntlmrelayx) with exponential backoff restart, /proc resource monitoring, process disguise via prctl, health check callbacks, graceful SIGTERM->SIGKILL shutdown
- scheduler.py: Cron-like task scheduler with jitter, thread pool execution, enable/disable/run_now controls
- resource_monitor.py: System + per-process RAM/CPU/disk/thermal monitoring, OOM kill lowest-priority module, thermal shedding at 70C
- kill_switch.py: 7-phase wipe sequence (stop procs, corrective ARP, LUKS destroy, shred keys, zero-fill, clear RAM, reboot), boot flag for interrupted wipe resume, dead man's switch
- modules/base.py: BaseModule ABC with start/stop/status/configure/health_check interface contract
