Description

The op-reth documentation currently lives in the upstream reth repository. Now that op-reth is part of the optimism monorepo, the OP Stack-specific documentation should be ported over and maintained here.

Scope

• Port all OP Stack documentation pages from reth (OP Stack running guide, sync FAQ, full op-reth CLI reference).
• Set up a Vocs-based documentation site under op-reth/docs/vocs/.
• Add justfile recipes for building and previewing the docs.
• Add a CircleCI job to build the documentation on CI.
• Add bun to mise.toml for the docs build toolchain.
