Adds dev-only counters, with no behavior change, to answer the open
questions from the migration plan before touching the transport:
- frontend.state/get-invoke-stats: per-thread-api-method count/total-ms/
max-ms for every <invoke-db-worker call, to census how many invokes a
typical navigation generates and their latency distribution.
- db-worker-node: per-repo in-flight /v1/invoke counter that logs a new
concurrency high-water mark, to check whether concurrent client writes
actually overlap before deciding on a write queue.
- subs-loader/get-stats: dedup-hit vs new-entry counts for load!, and
batch-size distribution per slot kind at flush, to check whether
in-flight snapshot requests are already deduplicated and whether the
{:children 25 :resources 25} limits are worth raising for network RTT.
Verified with clojure -M:cljs compile app and compile db-worker-node
(0 warnings on both).
