Problem

FTS5, vector search, and graph proximity run sequentially in brain_search().

Location

src/index/brain.rs:94-96

Solution

Use std::thread::scope to run signal sources concurrently.

Expected Impact

Save 30-50ms.

Dependency

Blocked by #407.

    Superseded. Brain search is already fast (~5ms via MCP). Parallel signal sources would add complexity for marginal gain at this scale. Closing as not needed.
