Default node position for spine/core/border-leaf/leaf/access is now a
Y-tier by role (parsed from hostname, same trust level as the site
parsing from #49) with X grouped by site within each tier, replacing
the flat site-grid heuristic.
Position specifically is now read from the live Grafana dashboard before
computing anything, so a node manually drag-and-dropped in the UI keeps
its position across regeneration -- only nodes with no live position yet
(new devices, or first-ever run) get the layered default. Devices removed
from the topology are simply absent from this run's output, so no
orphaned position/link reference is possible.

generate_weathermap.py now emits only the weathermap panel (targets +
options.weathermap) and merges it into a manually-authored dashboard base
(configs/grafana/dashboard-base.json) at a reserved slot panel, keeping
the base's gridPos so layout stays manual. The BGP sessions table,
ports/interfaces table, throughput graphs, and template variables move
out of the script entirely into that base file.
Verified zero regression: merged output is identical to the prior
generator-only output except for JSON key ordering, and all panel
queries re-validated via /api/ds/query.

Root README now just links to it. Also updates the default
GRAFANA_WEATHERMAP_PLUGIN_ID to the fork actually installed
(tamirsuliman-weathermap-panel), confirmed while validating #48.
