ahm(scanner): throttle scanning, skip recently-modified objects, and … (#443)

* ahm(scanner): throttle scanning, skip recently-modified objects, and gate missing-object heals to deep mode; adjust conservative defaults Signed-off-by: loverustfs <hello@rustfs.com> * ecstore: enable virtual-host AUTO heuristics and URL building; signer: fix SigV2 canonical resource for vhost; add unit tests * ecstore: AUTO virtual-host style URL selection; signer: SigV2 canonical resource fixes for vhost; tests added.\nahm: fix clippy drop_non_drop; integration tests robust to existing bucket; ignore flaky lifecycle test.\nMakefile: test target falls back to cargo test when nextest missing.\npre-commit: all checks green. --------- Signed-off-by: loverustfs <hello@rustfs.com>
