v1.0.42

Changes

• Whitelist dedup: wl1_push()/wl2_push() helpers enforce uniqueness — no more duplicate WL entries
• Startup LAN probe: Sends path request on LoRa at boot to discover local devices immediately
• FWD-CHECK format: Now shows FROM interface + zone, TO dest + zone — no more ambiguous fields
• Heap report: Periodic heap stats every 30s (WL dump suppressed)
• Stack increase: Loop task stack 8KB → 16KB for stability
• Logging overhaul: Unified [TYPE] - FROM: (zone) - TO: (zone) format across all packet log lines
