feat(group): add sync pipeline, CLI, MCP tools, and monorepo fixture

Browse source 
Wire extractors into the sync pipeline with service boundary detection.
GroupService provides high-level API for all group operations.

- Sync pipeline: orchestrates extraction (HTTP, gRPC, topics) with
  service boundary assignment and exact matching
- GroupService: groupList, groupSync, groupContracts, groupQuery,
  groupStatus (groupImpact deferred to cross-repo follow-up PR)
- CLI: group create/add/remove/list/sync/contracts/query/status
- MCP tools: group_list, group_sync, group_contracts, group_query,
  group_status
- Monorepo fixture: 3 services (auth/orders/gateway) connected via
  gRPC + Kafka + HTTP — all intra-repo cross-links discovered
- Documentation: CLI commands and MCP tools added to both READMEs
