feat(store): include HANDLES/HTTP_CALLS in process detection BFS

Process detection now follows HANDLES, HTTP_CALLS, and ASYNC_CALLS edges
in addition to CALLS when building Louvain communities and running BFS
from entry points. Previously only CALLS edges were traversed, making
Express/Hapi route→handler flows invisible to process detection.

Changes:
- Louvain edge loading query: type IN ('CALLS','HANDLES','HTTP_CALLS','ASYNC_CALLS')
- BFS from entry points: 4 edge types instead of 1

Tested: Express monorepo with 158 routes went from 3 to 4 detected flows,
with routes now participating in community detection.
