glm-5.3-flash ad975408e7 feat(adapters): from_jsonschema single-endpoint adapter + shared forwarding core
- src/adapters/forward.rs: shared HTTP forwarding core (extracted from
  old from_openapi) — HttpServiceConfig/HttpAuthScheme, build_request
  with capabilities-based credential injection (no env vars), forward
  + forward_stream (SSE projection), parse_sse_frames
- src/adapters/from_jsonschema.rs: FromJsonSchema OperationAdapter
  (ADR-066) — one registration per call, FromJsonSchema provenance
  (leaf, Internal default), Sub -> HandlerKind::Stream (text/event-stream)
- adapted to alkcall 0.1.1: OperationType::Sub, alkcall::client
  adapter traits

Verified: cargo test (106 lib tests), clippy -D warnings, fmt.

## Description
Port `adapters/from_jsonschema.rs` from
`/workspace/@alkdev/alknet/crates/alknet-http/src/adapters/from_jsonschema.rs`
per ADR-066: caller supplies OperationSpec + HttpServiceConfig + path
template + method; one HandlerRegistration with a reqwest forwarding
handler (same shape as from_openapi's), FromJsonSchema provenance
(leaf, Internal default). Sub op type → StreamingHandler expecting
text/event-stream. Shares the forwarding-handler code path with
from_openapi.
## Acceptance Criteria
- [x] Adapter ported; one registration per call, correct provenance
- [x] Forwarding round-trip test against a local mock server
- [x] `cargo test` passes
## References

## Notes
> Agent fills during implementation.
## Summary
Ported `src/adapters/from_jsonschema.rs` per ADR-066, plus the shared
forwarding core it depends on:
- `src/adapters/forward.rs`: extracted from old from_openapi —
HttpServiceConfig/HttpAuthScheme, build_request (path templates,
query split, body key, credential injection from
OperationContext.capabilities), forward (2xx -> JSON/text/bytes
envelope; non-2xx -> declared code or HTTP_<status>), forward_stream
(SSE -> ResponseEnvelope stream, ADR-049), parse_sse_frames.
Pre-positions the from_openapi port to reuse the same core.
- `src/adapters/from_jsonschema.rs`: FromJsonSchema OperationAdapter —
one HandlerRegistration per call (spec + path template + method),
FromJsonSchema provenance (leaf, composition_authority None,
scoped_env None, Internal default), Sub op type -> HandlerKind::Stream
expecting text/event-stream.
Adaptations for alkcall 0.1.1: OperationType::Sub (not Subscription),
adapter imports via alkcall::client::{AdapterError, OperationAdapter}.
11 tests: registration shape, handler kinds (Query/Sub/Mutation),
build_request bearer-from-capabilities + path/query split, forwarding
round-trip vs local mock server (200/404/500), SSE subscription stream,
no-env-vars invariant. 106 lib tests green.
