fix(knowledge): reject a whitespace-only copilot query explicitly

waleedlatif1 · waleedlatif1 · commit 07d80d0431ea · 2026-07-31T12:11:04.000-07:00
The shared dispatch treats a whitespace-only query as absent and throws when no
tag filters accompany it, where the previous vector-only call would have
embedded the blank string and searched. Tighten the existing guard so the tool
returns its normal message instead.
