Add flow steps and built-in services resources for RAG (v1.8.0)

New MCP resources (2 added, 5 total):
- wm://docs/flow-steps-reference: Official IBM documentation for all
  7 flow step types (INVOKE, BRANCH, LOOP, MAP, SEQUENCE, REPEAT, EXIT)
  with properties, behavior rules, failure conditions, data mapping
- wm://docs/builtin-services: Complete input/output signatures for
  pub.string (32 services), pub.math (22), pub.list (6), pub.date (12),
  pub.flow (20+), plus Kafka listener configuration

These resources enable AI assistants to correctly construct flow services
by referencing the documentation when building complex patterns.

223 tools + 9 prompts + 5 resources. 155/155 E2E tests passing.
