docs: update incremental benchmarks (3.9.5) (#1008)

* docs: update incremental benchmarks (3.9.5)

* docs: note v3.9.5 engine-null cause in incremental benchmarks (#1008)

Both engines returned null for 3.9.5 because their workers hung past
the 10-minute per-engine timeout in scripts/lib/fork-engine.ts and were
killed before returning results. Add a NOTES block explaining this and
noting that 3.9.5 is consequently absent from the version-history
comparison table, mirroring how 3.5.0 documented the same scenario.

+<!-- NOTES_START -->
+**Note (3.9.5):** No build/rebuild metrics for this release (both engines null) — only import resolution data was collected. Both the WASM and native workers reached the 1-file rebuild phase and then hung past the benchmark's 10-minute per-engine timeout (see `scripts/lib/fork-engine.ts`), so each was killed (`SIGKILL`) before returning results. Import resolution is unaffected because it runs in the parent process and doesn't depend on the full build. 3.9.5 is consequently absent from the top-level version-history comparison table since there are no build-time figures to compare against prior releases. The workflow run is [here](https://github.com/optave/ops-codegraph-tool/actions/runs/24863501577); the root cause will be investigated and the numbers backfilled in a follow-up if possible.
