fix(ruvbot): resolve typecheck and test failures

- Create missing learning/memory/MemoryManager.ts with Embedder and VectorIndex interfaces
- Fix core/index.ts to re-export memory types from learning module instead of non-existent core/memory
- Fix HybridSearch to await async vectorIndex.add() call and handle empty queries
- Fix MockSlackWebClient name collisions (users, files, reactions private Maps shadowed by API objects)
- Fix MockRouter path matching to properly split method:path keys with param colons
- Fix SkillRegistry updateMetrics calculation for success rate
- Fix test mocks to match async interface signatures (VectorIndex, Embedder)
- Update skill test latency calculation to use performance.now() for sub-ms precision

Test results: 561 passing (previously 287), 10 remaining edge case failures
