唐小鸭 46a387dffe fix(replication): resolve drifted replicas via a target version ledger
A replication target that mints its own version ids (Wasabi, AWS S3)
never answers to the source uuid, so every version-addressed mutation
after the initial PUT failed forever: permanent version deletes answered
NoSuchVersion every heal cycle, and tag / retention / legal-hold updates
re-PUT the object, minting one more target version per update
(rustfs/backlog#2340).

Record the id the target assigned as a per-target ledger on the source
version (replication-target-version-<arn>, written through the existing
status writeback) and resolve every later mutation through it: version
deletes DELETE the ledger id, metadata updates go through the
metadata-only Object Lock and tagging APIs. Replicas written before the
ledger existed are located by exact key and ETag, minus the candidates
other generations of the key already claim through their own ledgers; an
ambiguous remainder is refused with a backoff instead of guessed, since a
wrong pick would destroy a live generation. A fresh write never consults
content identity. NoSuchVersion on a version-addressed DELETE counts as
purged.

The fake target gains the Wasabi shape (404 NoSuchVersion on an unknown
id, per-version Object Lock APIs) and the matrix covers the three
mutation classes plus the same-bytes generation case.
