Separate library and service CLI args; flatten lib args into service args

[teddyknox]

Modifies no behavior; not a breaking change

• Split RollupBoostArgs into RollupBoostLibArgs (library) and RollupBoostServiceArgs (service).
• RollupBoostServiceArgs flattens RollupBoostLibArgs via clap; existing CLI flags unchanged.
• Updated server constructors and tracing/metrics init to use new types.
• CLI users: no changes. Library users: migrate to RollupBoostLibArgs / RollupBoostServiceArgs.

Pull Request Overview

This PR refactors the command-line argument structure by splitting RollupBoostArgs into two separate types: RollupBoostLibArgs for core library functionality and RollupBoostServiceArgs for service-level configuration.

• Introduced RollupBoostLibArgs containing core arguments (builder, l2_client, execution_mode, etc.)
• Created RollupBoostServiceArgs as the top-level parser that embeds RollupBoostLibArgs via a lib field
• Updated all usages to access core arguments through the lib field where appropriate
