唐小鸭 b9b2aa0b76 fix(ecstore): retry rename preparation on a pruned parent (#7005)
A completed multipart upload's staging cleanup prunes empty parent
directories up to the volume root, which removes shared prefixes such as
`data-movement/` and the per-object `<sha>/` while a concurrent
new_multipart_upload builds its destination chain below them. The writer
holds a descriptor to the pruned component, so its next handle-relative
mkdirat fails NotFound. Because rename never retried NotFound, the cleanup
fan-out failed several disks in the same window and broke write quorum.

Give rename preparation its own retry rule: a NotFound is retried once per
component below the base directory, so a rebuilt walk outlasts a pruning
walk, which removes ancestors monotonically upward and stops at the base.
A destination whose parent is the base keeps NotFound terminal, so
speculative cleanup renames still fail fast, and the base is only ever
opened, never created, so a genuinely missing base still fails. The rename
itself keeps its own budget and its unchanged NotFound-is-terminal rule.
