Move weathermap generator docs to scripts/README.md

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.

 ### Weathermap panel generation (dashboard-as-code)
 
-`scripts/generate_weathermap.py` generates a [weathermap-ng](https://github.com/allamiro/grafana-network-weathermap-ng)
-panel from live IPFabric topology + gnmic/Prometheus metrics, and writes a full
-Grafana dashboard-as-code JSON to `configs/grafana/weathermap-dashboard.json`
-(committed to Gitea as the source of truth, same pattern as the retired Flow
-Panel YAML). See issue #48 for the schema research this is built against.
-
-```bash
-export IPFABRIC_URL=https://<ipfabric-instance>
-export IPFABRIC_TOKEN=<token>
-python3 scripts/generate_weathermap.py                 # writes the JSON only
-
-export GRAFANA_URL=https://<external-grafana-instance>
-export GRAFANA_TOKEN=<token>
-export GRAFANA_DATASOURCE_UID=<prometheus-datasource-uid-in-grafana>
-python3 scripts/generate_weathermap.py --provision      # also provisions via the Grafana API
-```

-- Re-run after any topology change (`evpn-lab.clab.yml`) to regenerate and re-provision.
-- Node/link topology comes from IPFabric (`/tables/inventory/devices`,
-  `/tables/interfaces/connectivity-matrix`); node positions are computed as a
-  simple site-grouped grid (dc/core/campus bands) since IPFabric has no
-  layout data.
-- IPFabric reports abbreviated interface names (`Et11`) while gnmic exposes
-  full OpenConfig names (`Ethernet11`); the script aliases known prefixes
-  (`Et`→`Ethernet`, `Po`→`Port-Channel`, `Lo`→`Loopback`, `Vl`→`Vlan`,
-  `Ma`→`Management`) and cross-checks the result against the live exporter,
-  logging (not silently dropping) any link whose aliased name has no matching
-  series — the actual fix for a real mismatch belongs in gnmic interface
-  aliasing (#43), not in this script.
-- `.100`/`.200` subinterface rows in the connectivity-matrix (802.1Q tags used
-  for the gold VRF stitching on Core) are excluded — they ride the same
-  physical port as their parent interface and gnmic only exports physical
-  interface counters.
-- The Grafana panel plugin id (`GRAFANA_WEATHERMAP_PLUGIN_ID`, default
-  `allamiro-weathermap-panel`) is a placeholder — confirm it against the
-  actually installed plugin before provisioning.
+`scripts/generate_weathermap.py` generates a weathermap-ng Grafana panel from
+live IPFabric topology + gnmic/Prometheus metrics. See
+[`scripts/README.md`](scripts/README.md) for usage and details.
