test(query): assert the CLI query call site wires graph_path (#2789)

The header logic is unit-tested, but only a real subprocess run proves the CLI
query command actually passes the resolved graph path through — the wiring that
was the point of #2789. Cover both the under-CWD relative form and an explicit
--graph outside the CWD shown in full. Plus 0.9.47 changelog entry.

 - Feature: JavaScript/TypeScript factory functions that assign callable members to a local object literal (`const api = {}; api.foo = fn`) now keep those members in the graph — the API object is modeled beneath its factory and the assigned functions attach as methods, including arrow-function assignments and their intra-factory call edges. The owner is minted only for identifiers proven to be object-literal bindings in the enclosing function, so arbitrary receivers do not reintroduce the phantom-owner flood, and the factory's `contains` edge is emitted once no matter how many methods hang off the object (#2745, thanks @rajanpanth).
 - Fix: `graph.json` field order is now stable across a read-rebuild round-trip, so re-running `graphify update` on an unchanged graph produces a byte-identical file instead of reshuffling node and link keys (#2582, thanks @C0KERNEL).
+- Fix: `graphify query` now names the graph it opened and its node count at the head of the answer (relative to the CWD when the graph is underneath it, absolute otherwise), so a query run from a parent project no longer silently answers from the wrong corpus with no indication which graph was used (#2789, thanks @abhay-codes07).
 - Fix: the `claude` backend no longer crashes with `AttributeError: 'ThinkingBlock'` when an extended-thinking response leads with a thinking block; the first text block is read instead (#2697, thanks @mdshzb04).
 - Fix: `graphify update` / `save_manifest` no longer rewrites `manifest.json` timestamps on a no-op run, so `graphify-out/` stops showing as dirty (and stops producing a trailing graph commit) when nothing changed; a genuine change still updates and persists (#2838, thanks @hopstreax).
 - Fix: a C# 12 primary constructor's parameters are now walked, so `class Svc(IRepo repo)` emits the `references` edge to `IRepo` and calls through `repo` resolve — previously the class silently dropped its dependency; built-in and type-parameter types are not fabricated (#2829, thanks @brobl2008).
