issue: #1138
Improved Knowledge search relevance and partial-query handling by tuning frontend threshold defaults and backend hybrid query behavior.
Before:
Default scoreThreshold was effectively 0 when not provided, so low-relevance files were often included.
Short partial queries (like vita) often returned nothing.
Unique terms could still return unrelated files due to semantic spillover.
Returned total could reflect raw backend hits instead of post-filtered displayed results.

Now:
Default scoreThreshold is 1.25 (frontend), with dynamic relaxation to 1.0 for short single-token queries (<=4 chars).
Backend keyword branch is stricter (operator: and, fuzziness: AUTO:4,7) and includes bool_prefix support for partials.
Added exact-text file preference: if query appears verbatim in specific files, results are narrowed to those files.
Fixed exact-file filtering robustness (only valid string filenames considered).
total now matches the actual filtered results shown (len(chunks)).
