Local benchmark

Single producer to a local nats-server v2.14 on the same host, 200,000 messages of 128 bytes, 3 iterations per backend. Stream purged between runs. Numbers will vary on different hardware, network, and stream configurations; treat as a relative comparison only.

Backend	Min	Median	Max	vs Serial
Serial	7,541	7,746	7,768	1.00x
Concurrent	94,965	95,481	96,724	12.33x
Publisher	136,733	137,082	139,655	17.70x
FastPublisher	141,992	147,359	147,584	19.02x

Reproducible via tools/OrbitPublish compare.

Synadia.Orbit.PCGroups v1.0.0-preview.6

What's new

• Multiple filters per consumer group: Static groups use Filters (string array), elastic groups use PartitioningFilters array of {filter, partitioning_wildcards} pairs
• Empty PartitioningFilters: Empty array defaults to > with full-subject partitioning (requires NATS 2.12+)
• Cross-language interop: JSON config in KV is now interoperable with orbit.go pcgroups/v0.2.0 and Java

Breaking changes

• Static config: Filter replaced by Filters (string array)
• Elastic config: separate Filter/Filters/PartitioningWildcards replaced by PartitioningFilters array
• Full-subject partitioning uses empty partitioning_wildcards array [] instead of [-1] sentinel
• Partition filter format is {partition}.{filter} (e.g. 0.orders.*) instead of {partition}.>

Thanks to @colprog for driving the multi-filter work and pushing this forward!
