/**
 * a2a/server.ts -- GoldenPipe A2A (Agent-to-Agent) protocol server.
 *
 * Node-only: uses node:http, node:crypto. NOT edge-safe.
 *
 * Port of goldenpipe/a2a/server.py. Mirrors the sibling GoldenFlow / GoldenMatch
 * TS A2A servers for structure (agent card at /.well-known/agent.json, skill
 * dispatch, task lifecycle). Skills delegate to the GoldenPipe MCP tools via
 * `handleTool`, exactly as the Python server delegates to its MCP tool functions.
 *
 * Endpoints:
 *   GET  /.well-known/agent.json   - agent card (4 skills)
 *   GET  /health                   - liveness probe
 *   POST /tasks                    - create a task (skill + params)
 *   GET  /tasks/{id}               - fetch task status/result
