NI Compute

First maintainer-reviewed pass for SN27 (previously candidate-discovered/unreviewed, categories empty). 3 of 4 surfaces had no probe config at all -- the registry-wide gap tracked in #5932 -- fixed. Investigated the on-chain SubnetIdentitiesV3 native_name 'Orion' (also shown by Taostats) as a possible rebrand, matching the pattern used for prior confirmed pivots (e.g. SN3 Templar/Crusades): unlike that case, nothing here corroborates it -- the operator's own live repository, W&B project, and config data are all still the original GPU-compute marketplace, and the operator domain (neuralinternet.ai) is currently unreachable rather than repointed. Not renaming on a single, uncorroborated on-chain field; documented in gap_notes for a future pass to revisit if independent confirmation appears. Also confirmed the GitHub org's platform-level rename to 'Nodexo' (github.com/neuralinternet now reports org name 'Nodexo'), matching the provider field already used on this subnet's community surfaces, but left the subnet name unchanged since a same-named, unrelated subnet already exists at netuid 106.
