preprocess made three LLM calls back to back. The safety check needs the rephrased text so it must follow the rephrase, but language detection reads the raw user input and does not -- so those two now run concurrently, saving one round trip on every message, on the path every profile shares. Idea from @bleedblack1 in #111. That patch parallelised the same two calls; this is the same change written against current main, since the PR predates 34 commits and its diff no longer applies. Two tests, both checked against the sequential version to confirm they fail on it: one asserting the two calls actually overlap in wall-clock time, one asserting the rephrase still completes before the safety check starts, which is the ordering constraint that must not be lost.

Problem
Preprocessing steps were executed sequentially, causing unnecessary latency.
Solution
Replaced sequential execution with parallel processing using asyncio.gather.
Impact
Reduces preprocessing latency by executing independent steps concurrently.
