fix(java): list dependencies' implementations after the project's in Go to Implementation

Go to Implementation on a type or method declared in a dependency (Runnable, a Spring interface) listed only the project's implementations once the project had one. openidea.java.implementations (java-usages 1.5.0) now answers {locations, complete}: complete when the type is declared in the sources, which no dependency implements. Its search also covers the project's Kotlin classes attached by the Kotlin bridge.

When the answer is not complete, ide-lsp passes those found first to the new lsp_goto_implementation channel and runs the standard request for the rest. The chooser opens with the project's implementations ("1 found, searching…") and fills in the dependencies' when the search ends; closing it cancels the search. Gutter markers keep the source-only answer for project types.
