fix(resolution): calls through an imported singleton resolve to the method (#1315)

reproStore.notifyJoinGuildStatus() after `import { reproStore }`
resolved its calls edge to the exported CONSTANT (resolvedBy:'import'),
while the identical same-file call resolved to the method via
local-variable receiver inference (#1108) — so `callers <method>`
missed every cross-file use and a widely-used method could look
unused (#1292).

resolveViaImport's member-descend now handles imported VALUES alongside
the #825 static-member case: when the base resolves to a
constant/variable, the value's type is inferred from ITS OWN
declaration lines in the exporting file (the shared #1108 pattern
table: `= new T(...)` initializers and type annotations) and the member
is resolved AND VALIDATED on that type via resolveMethodOnType. A
failed inference or validation keeps the existing constant edge —
never a fabricated one. Calls only; plain member reads still reference
the value.

excalidraw control: byte-identical graph (10,653 nodes / 19,483 calls
edges before and after).

Fixes #1292
