Give the counter sample integer MessagePack keys

Browse source 
CounterState in samples/eve-browser-network used string [Key]s, which the
registry rejects at registration, so the provider threw on open. Keys are now
0 counterId, 1 count, 2 receipts. The payload becomes a MessagePack array, so
the browser lowerer reads count positionally instead of by field name. The
getting-started chapter carried the same string-key shape and is corrected to
match.

BenchItem needed nothing: a5d1be6 already marked it [MessagePackObject]; the
earlier scan rejection came from a stale benchmark build. After rebuilding,
both types register.

No .cc stores exist under samples.
