v0.143.0 — guest RAM resize UI (R-24) — MinAgent: 0.90.0
The customer sees the guest's current memory + allowed range on the Rendszer settings page and resizes it. The controller proxies + maps the agent's machine code to Hungarian; the agent (felhom-agent v0.90.0) enforces every bound and applies live (no reboot). agentapi: GuestMemory + ResizeMemory; ruled 412 -> *MemoryRefusedError (code+bounds); pre-0.90 agent 404 -> typed *StatusError. Capability: FeatureGuestMemoryResize + featureMinAgent 0.90.0 + a featureProbes row (type-asserts GuestMemory so the shared SupportProber/netAgent are untouched). UI (internal/web/system_memory_handlers.go, settings_system.html): "Szerver memoria (RAM)" card + number input; POST /api/system/memory/resize -> capability gate -> agent -> flash. JS confirm only on shrink. Code->Hungarian map; agent-outdated hides the control; agent-unreachable falls back to the guest's /proc/meminfo. Agent English never shown raw. Tests: agentapi (decode, 404, refusal-code, capability table) + web handler (success/ below_usage_floor/agent_outdated). Gates + go build/vet/test all pass.
