HashBurst Node Installer v2.1.2 — GitHub-ready stable candidate

v2.1.2 is a safety/packaging release based on the production-validated v2.1.1 deployment.

Fixed

Storage aggregator port safety
- systemd unit now uses HB_AGGREGATOR_PORT=8094.
- hb_aggregator_server.py now defaults to 8094.
- unit sets HB_AGGREGATOR_TIMEOUT=3 to prevent an unreachable edge node from delaying the public aggregate for the previous 6-second default.
- 8093 remains reserved for the mining aggregator.
Fail-safe offline classification
- online nodes derive capacity class from their validated role.
- offline nodes use explicit configured capacity_class, then configured role.
- an offline/unclassified node now reports capacity_class: "unknown"; it never implicitly becomes committable.
Static node configuration clarity
- example configuration includes explicit role and capacity_class for primary, secondary and edge nodes.
- edge nodes should explicitly use role: "edge" and capacity_class: "best-effort".
Explorer integration
- adds an idempotent CSP-safe patcher for existing public explorers.
- maps the storage panel to capacity_committable_gb and capacity_best_effort_gb.

8091 — storage node public summary (restricted to aggregator where directly exposed)
8093 — mining aggregator
8094 — storage network aggregator
18094 — optional temporary dry-run port only

Validated topology values remain:

committable: 5520 GB
reserved stakeholders: 3736 GB
free sellable: 1784 GB
offline edge contributes 0 GB to best-effort online capacity and never increases sellable capacity
unreachable edge timeout approximately 3 seconds
