Resolve conflicts with upstream proof API updates while retaining the removal of redundant proof blocks and the proof replacing the range-end assumption. Use verus_spec for the range return contract requested in PR asterinas#739. The method was already verified; the contract exposes its exact result to callers. No additional executable changes relative to main. Validation: focused kvirt_area verification (14 verified, 0 errors), full make, verusfmt --edition 2024 --check on kvirt_area.rs, and git diff --check pass. make fmt formats the target but skips seven other files due to existing formatter parsing failures.

rlimit is deterministic across runs; wall-time / smt-run have run-to-run jitter. Negative rlimit = improvement.
