Metadata

Commit message: feat(server): implement A2A HTTP transport for server mode
Branch name: feat/v3.8.0-a2a-http-transport
Parent Epic: #8677
Milestone: v3.8.0

Background and Context

The A2A HTTP transport enables server mode where the agent exposes a single JSON-RPC endpoint over HTTP. This transport is the primary mechanism for remote agent-to-agent communication in production deployments.

Expected Behavior

Current Behavior

No A2A HTTP transport exists for server mode.

Expected Behavior

A2A HTTP transport is implemented and functional
A single JSON-RPC endpoint is exposed over HTTP
The transport correctly handles HTTP request/response lifecycle for JSON-RPC 2.0 messages

Acceptance Criteria

A2A HTTP transport is implemented
Single JSON-RPC endpoint is exposed over HTTP
Integration tests pass with coverage >= 97%

Subtasks

Implement A2A HTTP transport layer
Implement single JSON-RPC endpoint
Write integration tests
Verify coverage >= 97%

Definition of Done

This issue should be closed when:

A2A HTTP transport is fully implemented and reviewed
Single JSON-RPC endpoint over HTTP is functional and tested
All integration tests pass with >= 97% coverage
Code has been reviewed and merged into the feat/v3.8.0-a2a-http-transport branch
Parent Epic #8677 dependency is satisfied by this implementation
