The previous regression tests in test_entities.gd only constructed their
own LogPlayer and never touched the seed logs the real call sites build
— reverting main_window_shell.gd:124 to the broken 3-arg call still left
the whole suite green. Not a real regression guard.
Now assert against node._log.player in the shell test and against the
two dev-harness scenes' seed logs (narrate_harness, npc_harness — both
cheaply testable via instantiate + add_child_autofree, no scaffolding
needed). Proved the new shell assertion fails when the call site is
reverted to the 3-arg shape (226/227, one failure), then passes restored
(227/227). Removed a redundant ctor test from test_entities.gd; kept the
one that exercises the exact broken-shape call.
