get_tree resolves a bare space name to a same-named page in Main before the top-level space

The man page says a bare name "resolves to Sales.WebHome when Sales is not a page". The check for "is a page" runs relative to the current (Main) space, so any stray page in Main with a space's name silently shadows the whole space. The response gives no hint that a space of that name exists, so the agent gets a confident wrong answer.

Expected: A bare name that matches a top-level space (i.e. <name>.WebHome exists) should resolve to the space, or the response should mention the ambiguity ("a top-level space named TaskTracker also exists; pass TaskTracker.WebHome").

Actual: Silent resolution to the Main-space page.
