v0.4.12 — working MCP signal tools + MCP billing parity

What's Changed

• MCP signal tools fixed — telemetry_get_signals_time_series and telemetry_get_latest_signals previously returned empty data (static mcpgen queries selected only timestamp/lastSeen). They now take a signal list (signalRequests/signalNames) and render the selection set per call via server-garage v0.4.0 SelectionTemplate + ToolOnly args. Startup fails if mcpgen output renames either tool.
• MCP extension parity — the MCP executor now shares the HTTP GraphQL server's extension set: DCX credit tracking, FixedComplexityLimit(100), query recording, metrics, error presenter. MCP tool calls were previously unbilled, unrecorded, and uncapped.
• server-garage v0.1.1 → v0.4.0, model-garage v1.0.13.
