cosmos-hub (gaiad): add compose + init.sh + cometbft.Dockerfile

First pure-cosmos chain (validates the §2 cometbft-common.sh lib via real gaiad init). Single-binary CometBFT client serving :26657 (dshackle chain=cosmos-hub). Statesync bootstrap (polkachu) since genesis-replay across gaia governance upgrades is impractical. gzipped genesis. v25.3.2 (live chain version; registry's v27.4.0 not on ghcr). Params (chain_id/genesis_url/statesync_rpc/seeds/min_gas) from context.yml. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
