unified-zig-api: extend (not rebuild), add missing API surfaces, share via a top-level repo, evaluate hard-groove deep-connect to http-capability-gateway

[hyperpolymath]

Finding (audit): the Zig unified adapter already exists

• developer-ecosystem/zig-api/ (unified-zig-api) unifies 11 services (ambient_ops, boj, burble, echidna, gossamer, groove_bridge, hypatia, idaptik, reposystem, stapeln, verisimdb) behind a gnosis HTTP gateway (replaces v-grpc + v-rest) + a 64-slot connector pool, with Idris2-proved ABI.
• zig-ecosystem/connectors/zig-groove-bridge/ handles 12 API types (rest, grpc, graphql, json-rpc, websocket, mqtt, amqp, coap, soap, capnproto, sse, groove).
• ⇒ Extend, do not rebuild. The V HexadecaSuite (16) stays in V (owner's gift, not converted).

Missing API surfaces to evaluate adding

• Observability (metrics/tracing hook)
• Auth/authz surface
• Streaming + backpressure (WebSocket/MQTT-class)
• Deadline/cancellation propagation
• Schema/capability reflection
• Coprocessor-dispatch verb (ties to Campaign: unified coprocessor backend (Axiom.jl pattern) + roll out to repos needing acceleration #110)

boj-server special features + hard-groove

features/boj-server/ (present in vcl-ut, burble, both affinescript packages, dev-ecosystem/ponyiser) documents: ephemeral transaction-bound gating, works with the http-capability-gateway (standalone, not forced). Evaluate hard-groove (per standards) to deep-connect adapter ↔ http-capability-gateway — note: all current estate Groove is soft, so hard-groove would be a new pattern — or a better mechanism.

Sharing

• Top-level repo to share it (e.g. hyperpolymath/unified-zig-api) — repo creation is outside the filing session's scope.
• Create canonical Axiom.jl as the optimised coprocessor backend (Campaign: unified coprocessor backend (Axiom.jl pattern) + roll out to repos needing acceleration #110) — likely a new repo.
