fix: handle pruned RPC state in SubQuery node

Browse Source 
Substrate nodes prune historical state by default (~256 blocks).
When SubQuery restarts and tries to fetch runtime version for old
blocks, it crashes with "State already discarded". This patch adds
a fallback to current runtime version when historical state is
unavailable, preventing crash loops on pruned RPC endpoints.

Also removes --pull from deploy workflow to avoid unnecessary
full rebuilds on every push.
