danusha2345andClaude Opus 5.5 b6379e6d5e fix(scala): an Outer.Inner(...) call reaches the Scala case class or object it builds
Scala qualified names carry no package (Outer::Inner), so a call written
Outer.Inner(args), a case-class or companion apply, found no type by its
written name. It fell through to the name strategies, and under a return
type annotation (def f(): WebSocket = WebSocket.Accepted(flow)) the
local-declaration reader took WebSocket for the receiver's type and handed
over an unrelated Java constructor, Other::Accepted::Accepted.

Before the receiver-word strategy, a Scala call whose member is
capitalized now resolves to the Scala type Outer::Inner when that is
unambiguous: every match in one file (a class and its companion), or one
in the call's own file; a class or trait wins over a same-named object.
It is recorded as instantiates for a class, as a call for an object. The
typed-receiver path no longer hands a Scala call another language's
constructor. Real Java static methods are still reached from Scala.

Validation:
- resolution.test.ts: 5 cases, 4 red on main; the fifth (a Scala call
  to a real Java static) passes on both and guards the Java side.
- A/B against main 81559dcc (with #1950 and #1936): scalachess +77/-0,
  http4s +371/-1 (the one a retarget from a wrong defaults::Host to the
  Origin.Host case class), playframework +291/-1 (the one a retarget:
  Writeable's HttpEntity.Strict(...) from the Java play.http constructor
  to the Scala case class), play-samples +2 (two case-class applies #1950
  unlinked from Java constructors); CMAK, click and gin identical. Every
  addition is a Scala case-class or object apply; sampled all right
  (Uci.Move, Header.Raw, H2Frame.Data, RemoteNode.Ip,
  ApplicationLoader.Context, Request.Connection over headers.Connection).
- Cost (http4s, median of 3 interleaved fresh indexes, on main
  69af19ac): wall 8.6 s on main vs 7.8 s, process CPU 27.5 s vs
  26.2 s, within noise. The A/B gave the same edges on both bases.
