Priority for function definitions in external files over local script

[Qwark-878]

Description: When a function is defined both in an external file (e.g., qlua.d.lua) and in the local script, Lua Language Server prioritizes the local definition. This behavior makes it difficult to use external annotations and documentation for functions that are implemented locally.

Steps to reproduce: Define a function in qlua.d.lua with annotations: lua Copy ---@param index number ---@return number|nil function OnCalculate(index) end Define the same function in the local script without annotations:

lua Copy function OnCalculate(index) -- Implementation end Hover over the function in the local script.

Expected behavior: Lua Language Server should prioritize the definition from qlua.d.lua for tooltips and documentation. Actual behavior: Lua Language Server uses the local definition, ignoring the one from qlua.d.lua. Proposed solution: Add an option to prioritize definitions from external files over local ones. For example, a setting like:
