docs: replace wiki with Pulsar-style multi-page documentation
Populates the wiki with 45 pages organized into 6 sections mirroring
Apache Pulsar 4.2.x:
- Get Started (5 pages): install, Docker, Docker Compose, Kubernetes
- Concepts and Architecture (12 pages): tasks, queue model, sharding,
leases, multi-tenancy, auth, persistence engine, consensus,
failover, deployment modes, architecture overview
- Sous Functions (6 pages): overview, concepts, get started,
configure workers, deploy, develop
- CodeQ IO (8 pages): overview, producer stream, worker stream,
REST API, persistence engine, group commit coalescer, raft
replication, mux transport
- Observability (5 pages): tracing, metrics, profiling, logging
- Performance (6 pages): single-node throughput, cost of HA,
multi-shard scaling, tuning knobs, bench harness
Plus Home, _Sidebar (left nav), and _Footer.
Voice: prose-first (>=70% prose ratio), CS-grounded vocabulary
(LSM, raft consensus, leader lease, group commit, FSM, WAL,
majority quorum, backpressure), zero buzzwords, port-labeled
diagrams (:8080 HTTP, :9091 worker gRPC, :9092 producer gRPC,
:7000 raft mux), file.go:line code citations, measured numbers
cited to bench files.
Replaces ~25 legacy pages (Storage-KVRocks, Use-Cases-*, etc.)
that predated the Pebble-only positioning and the Pulsar-style
multi-page structure.
