docs: update incremental benchmarks (3.8.0) (#748)

* docs: update incremental benchmarks (3.8.0)

* docs: add note explaining near-zero phase timings in 3.8.0 (#748)

The full Rust build orchestration pipeline (#695) moved parsing, AST
analysis, and complexity/CFG/dataflow computation into the native
engine, so these phases no longer run separately during JS-side
incremental rebuilds.
