Remove the unused TCP transport and dead CLI/simulation scaffolding and collapse scattered single-purpose modules into consolidated files across the dashboard, process, and simulation crates.
- crates/transport: drop the TCP transport (src/tcp.rs and its tcp feature), leaving only ed25519 identity and encoding utilities behind the iroh transport
- crates/dashboard: collapse actor_detail_html/actors_html/dashboard_html/topology_html into a single html.rs, drop command/parse.rs, and inline the trace types into lib.rs
- crates/process: fold driver, pipeline_types, queue, subscriber, waker, and local pipes/signal/wait into local/mod.rs, pipeline.rs, and a unified types.rs, consolidating the public re-exports
- crates/simulation: remove the ci subdirectory (local_sim, sim) and dead node/config/trace modules, and flatten the distribution subdirectory into top-level files
- crates/datastore: remove the unused store_cli, cli, and in-memory storage, and deduplicate crypto.rs across datastore and distribution (about 190 lines of shared code removed)
- crates/distribution: drop dead codec code and trim the messages module
