Move the lifecycle section off the clusters concepts page into its own guide under /clusters/, and expand it to cover what each stage looks like in the catalog: provisioning, hydrating, catching up, and steady state, plus the zero-replica and offline-replica states that interrupt them.

Moves the lifecycle section off the clusters concepts page into its own guide, and expands it with the catalog signals for each stage: provisioning, hydrating, catching up, steady state, plus the zero-replica and offline-replica states that interrupt them.
Closes EDU-89
Verification
Every query and output was run against the
v26.41.0emulator. That surfaced several corrections to the queries the concepts page shipped: they need ano.id LIKE 'u%'filter (otherwise ~33 built-in introspection indexes drown the result),mz_hydration_statusesretains stale rows for retired replicas so themz_cluster_replicasjoin is load-bearing,mz_materialization_lagis input-relative and reads00:00:00through a full-cluster stall, and status history must resolve names throughmz_cluster_replica_historyrather thanmz_cluster_replicas.🤖 Generated with Claude Code
