Function filterGraph

filterGraph(graph: Graph, opts: FilterOptions): Graph
Apply scope and metadata filters to a graph, returning a new sub-Graph.

Order: the metadata filters (repo/label/milestone/state) narrow the node set first; then scope widens or trims it — open keeps open nodes plus the closed endpoints of surviving edges, connected drops isolated nodes, all keeps everything. Any edge with a dropped endpoint is dropped.
Parameters
- graph: Graph
  the status-computed graph
- opts: FilterOptions
  the filter options
Returns Graph
a new filtered Graph with refreshed counts and meta.filtersApplied
Example
```
filterGraph(graph, { scope: 'open', label: ['bug'] }).nodes.length
  // => count of open bug issues plus their kept-edge endpoints
```
