feat: complete v0.2.0 must/should items — shared libs, e2e, federation, gRPC, subscriptions, hot-reload

Completes all v0.2.0 must and should items:
- Build 4 cartridge shared libraries (.so) with standard C-ABI interface symbols
- End-to-end order-ticket flow tests (happy path + negative cases)
- Umoja federation gossip protocol stub (11 C exports, 6 tests)
- gRPC-compat adapter with service/method paths and grpc-status header
- GraphQL subscription polling with ring-buffer event queue
- Cartridge hot-reload (unmount → verify hash → remount)
- Grade A production readiness tests (7 tests: concurrent, stress, capacity)

74 total tests (51 core + 23 cartridge), all passing.
