Adds a third symphony-bdk-http implementation on top of java.net.http.HttpClient, giving consumers a zero-third-party-dependency alternative to jersey2/webclient.
…(D12) symphony-bdk-http-jersey2 carries the largest dependency/CVE surface for a filter-chain benefit nothing in the codebase uses. Make the new jdk module the documented default for symphony-bdk-core and mark jersey2's public classes @API(DEPRECATED) as a soft, non-removing signal — no functional change, no forced migration.

Summary
symphony-bdk-http-jdkmodule implementing the BDKApiClient/ApiClientBuildercontract on top ofjava.net.http.HttpClient, giving consumers a zero-third-party-dependency alternative to the existing jersey2/webclient implementations.symphony-bdk-http-jersey2(param encoding, JSON serialization, tracing headers, file downloads, TLS/proxy config, retry-compatible exception translation), with two documented, deliberate gaps (read-timeout mapping, filter chain narrowing) called out explicitly.symphony-bdk-http-apicontracts or existing modules; Spring Boot starter wiring is explicitly out of scope for this change.This is an OpenSpec proposal only (
openspec/changes/jdk-httpclient-transport/) — no implementation code yet.Test plan
