Bulk rename miners

Use a deterministic template that remains unique within the farm.

Safe workflow

• Preview generated names before applying.
• Use a stable prefix for each location or hardware group and include a sequence or device-derived value.
• The Server rejects duplicate names; an existing fleet must continue from the appropriate sequence.

Batch safety

• Rename a small selection first and verify that external pool worker names behave as expected.

Logical name and system hostname

• RigeOS always updates its logical miner name.
• On regular Linux, Client attempts to synchronize the system hostname; missing systemd, hostnamectl or permission only leaves the logical name in place.
• Docker, Kubernetes and other containers keep the orchestrator-managed hostname. The RigeOS remote Shell prompt displays the logical miner name instead.
