slug resolution: derive from dRPC chains.yaml, no in-code name heuristics

Regenerated by the expand_config.py redesign (see vibe-node commit). Slug
corrections, each verified present in chains.yaml:
  soneium-minato-sepolia x5: soneium (MAINNET!) -> soneium-minato
  avalanche-fuji x5:         avalanche (MAINNET!) -> avalanche-fuji
  thundercore-venus:         thundercore (MAINNET!) -> thundercore-testnet
  core-pigeon:               core-pigeon -> core-testnet
  zircuit-garfield:          zircuit-testnet -> zircuit-garfield-testnet
  sonic-testnet x2:          sonic-testnet -> sonic-testnet-v2
  ronin-saigon x3:           (none) -> ronin-saigon
  everclear-sepolia x2:      dropped (chain shut down 2026-06-05)
fuse-spark x3 (hand-written, fuse has chains: null in context.yml): x-upstreams
REMOVED - Sparknet is absent from chains.yaml; it declared the mainnet slug.

Verified: 310 testnet composes, 0 wrong-slug failures (was 22); 0 mainnet
composes carrying a testnet slug; 0 mainnet slug changes.
