Improve `Ctrl+T` (`#` symbol search) result ranking by prioritizing project symbols over library symbols

[milic-marko]

When using symbol search via Ctrl+T in VS Code with Eclipse JDT LS, searching with # currently returns a mixed list of symbols from both the current workspace/project and external libraries/dependencies.

For large projects with many dependencies, relevant project symbols are often buried under symbols originating from libraries, making navigation slower and noisier.

It would be helpful if search results were ranked by relevance, with symbols/classes from the current workspace prioritized above symbols from external libraries.

Current Behavior

Searching for symbols using Ctrl+T and #:

• Returns symbols from:
  • current workspace/project
  • external JARs/dependencies
  • JDK classes
• Results appear intermixed
• Exact or highly relevant project symbols may appear below dependency/library matches

Example:

Searching for:

#RequestHandler

May produce results like:

org.springframework...RequestHandler
some.library...RequestHandler
my.project.api.RequestHandler

even though the project-local symbol is usually the most relevant result.
