Moves L2GNS, L2Curation, GNS and their helpers from packages/contracts into packages/subgraph-discovery, and repoints Ignition, pre-verify, Tenderly and deployment at it. Toolshed logs a warning for GraphCurationToken and SubgraphNFTDescriptor, the two new horizon address names. L2GNS (94.38% vs 95.06%) and GNS (68.18% vs 68.55%) read below their coverage baseline because forge counts more lines, and their unhit lines were also unhit by the old tests.

Replaced by revision 4 of the phase 1 plan: the frozen discovery contracts move to graph-token, and L2GNS and L2Curation are ported in Phase P. The RewardsHook and Multicall tests from this PR are reused in the new P3.
