GetObject on a versioned object returned NoSuchKey forever when the
.versions directory existed but carried no latest-version pointer (empty
Extended metadata) while real version files remained inside it. The
self-heal path only fired for a dangling pointer (present but referencing
a missing file), not an absent one, so doGetLatestObjectVersion fell
straight through and errored on every read.
- doGetLatestObjectVersion now calls recoverLatestVersionWithoutPointer
when the pointer is missing or empty. An absent pointer is the legitimate
signal that a pre-versioning or suspended-versioning "null" object is
current, so that object wins; only when it is absent do we rescan
.versions/ and rebuild the pointer from the version files present.
Transient rescan failures propagate instead of being masked as NotFound.
- selectLatestVersion derives the version id from the v_<versionId> file
name when the Seaweed-X-Amz-Version-Id attribute is absent, so version
files written outside the normal versioned-PUT path (replicated or
restored entries) are still promotable. The orphan diagnostic uses the
same detection so an entry can't be both promoted and counted an orphan.
