ESFEX v0.1.12

Manual node definition in Build & Connect: place node centroids by clicking the map or editing a table, with each node's Voronoi territory drawn live (clipped to the domain).
Voltage consistency (#18): voltage-less OSM lines now inherit a consistent voltage and only join same-voltage buses, with auto-transformers between co-located voltage levels.

Non-linear SSP trajectory: per-year SSP GDP/population growth is now wired into the grid-step forecast (no more near-linear demand).
Observed-demand validation: import per-node observed series, compare against the forecast (MAPE/RMSE/peak/energy/correlation + dashed overlay) and optionally apply a month×hour correction that preserves the SSP growth path.
Per-node forecast from the node panel: a new "Forecast" button runs the full forecast + validation + bus distribution scoped to a single node, adapting to whether the node already has electrical infrastructure. The obsolete standalone "Demand Estimation" workflow has been retired.
Step 3 layout now fits the default window.

Removed the non-functional per-node "Technologies" section from the node panel and the duplicate investment fields from the technology catalog — per-node × per-technology investment limits live solely in the Investment Portfolio (the values the optimizer uses).
The node technology dropdown now tracks the live system technology catalog.
Fixed the Investment Portfolio "Type" list to match the right-click menu (dropped the unsupported fuel_transport entry).

Behaviour options are now honoured: auto-open results after a successful run, and auto-save driven by an on/off switch.
"Validate before run" is now the single default flow (toggle removed).
New defaults for fresh installs: GitHub Light theme and auto-open results enabled.
