Local validator & tracing

Learning objectives

• Build and run a minimal local cluster or single validator config aligned with current repo docs.
• Identify log prefixes for gossip, TPU, TVU, blockstore—so Level 3 contribution targets real failures.
• Relate tracing hooks to the banking/replay module that follows.

Reading scaffold

Point to multinode-demo, validator/, or docs under docs/src in your clone. Next: Banking & replay pipeline.
