The completions handler kept a local copy of getTokenAtPosition plus three stale TODO comments noting the duplication, but the function is already exported from server/src/utils.ts (hover.ts and others import it from there). Drop the local copy, import the canonical one, and remove the now-meaningless comments.

What is the current behavior?

completions.ts keeps a local copy of getTokenAtPosition plus three stale TODO comments asking for the duplication to be cleaned up. The canonical version already lives in server/src/utils.ts and is consumed by hover.ts and other handlers, completions is the last duplicate.

What is the new behavior?

• Import getTokenAtPosition from ../utils in completions.ts (extending the existing import block).
• Delete the duplicated local function.
• Delete the three stale TODO/notes-to-self comments.

No behavioral change. 21 lines removed, 1 line added.

Does this PR introduce a breaking change?

• Yes
• No
