feat(scripting): add CLI runner, script harness, and examples

[yahgwai]

no-issue

Summary

Extends the zod schema (#690) work with some scripting tools

• Adds runScript boilerplate for quickly writing schema enhanced scripts that use the sdk
• Add a CLI for all current SDK functions, so that any SDK function can be invoked from the command line. eg:

npx tsx src/scripting/cli.ts getDefaultSequencerInboxMaxTimeVariation '{"parentChainId": 1}'

• Adds example scripts for some common workflows (createRollup, deployNewChain, transferOwnership, etc.). These are just example right now, but we'll soon extend the CLI with more general usage scripts, like deployNewChain

Not included for now

• Additional parsing libs. Now that we have zod schemas which will parse json, we can use existing tooling to convert yaml, env vars or cli args to json and than parse with the same schema giving scripts more options of what they expose to users.
• Describe() - we can add documentation to the schemas to give consumers and idea of what values to put into the params. Those descriptions can be accessed via a dry-run/help command or zod can be converted into json schemas to directly expose the documentation.
• Documentation and readme. Three sets of documentation is required: one for sdk maintainers, one for script writers and one for users of the cli.
• Extending the CLI with some standard useful scripts to be used by SRE/other consumers
