feat: surface miner nonce too high errors

This commit exposes the ErrNonceTooHigh at the execution level to
external users. Previously the error was mapped to ErrNonceTooLow to
match the mempool behavior. As this is a new error, and one not
currently exposed in L1, this could be a breaking change for some
applications depending on how the error messages are parsed.

feat: add v0 go batch submitter and gh actions integration

For some reason the log level environment variables aren't being picked
up, and neither is the default value for the flag being applied to the
final binary when run in docker. Remove this commit once a fix is
established.

Attempting to compile L1 and L2 get in the same binary produces a
symbole collision since the CGO names for the library methods are
identical. To avoid this, we simply reexport the L1 secp256k1 members
that rely on CGO.

feat: tweaks from final SDK behavior review

- Updates the HTTP response code metric to includes 200s
