* storage: make DeleteVolume errors inspectable with errors.Is
An absent volume wraps ErrVolumeNotFound and an only-empty refusal now
wraps ErrVolumeNotEmpty with %w instead of %v, so callers no longer have
to match on the message.

* volume server: return NotFound and FailedPrecondition from VolumeDelete
An absent volume maps to codes.NotFound and a non-empty volume under
only_empty to codes.FailedPrecondition, so a caller retiring a volume can
treat NotFound as already done. The store message is kept in the status
description because the EC empty-replica sweep still matches on it.

* wdclient: add LookupVolumeIdsAuthoritative
Bypasses the vid map and asks the provider directly, for callers where a
stale positive location is unsafe.

* filer: add LookupDirectoryEntries batch lookup RPC
Up to 4096 exact-path lookups in one call, resolved concurrently with
results in request order, plus one deduplicated location lookup for every
volume the returned entries reference and per-fid read tokens when the
filer signs reads. unavailable_volume_is_miss lets cache-style callers
take an entry whose volume has no live location as a miss, resolved
against the master rather than the filer's location cache.

* filer: test that an expired file entry is deleted on read

* filer: test that AssignVolume and CreateEntry resolve the same TTL rule

* master: refuse partial lookups while warming up
LookupVolume returned Unavailable during warm-up only when every requested
volume was missing. A batch mixing a reported volume with one whose server
has not reconnected yet came back as a partial answer with a per-volume
not-found, which a caller treating the master as authoritative reads as
gone. Any not-found during warm-up is now Unavailable, which callers
already retry.

* filer: build batch test requests instead of copying a proto message
Copying a generated message copies its internal mutex, which go vet's
copylocks check rejects.

* filer: match ErrNotFound with errors.Is and state the miss rule's contract
A wrapped not-found from the store would otherwise be reported as an
error rather than a miss. The comments now say why a nil location map is
the only sign of an unanswered lookup: the provider returns nil when it
got no answer and a populated map, with unserved volumes reported as
errors, when the master did answer.

* volume server: map absent and non-empty VolumeDelete errors in the Rust server
Matches the Go server: an absent volume is NotFound and an only_empty
refusal is FailedPrecondition instead of Internal, with the messages the
EC empty-replica sweep matches on.

* filer: test that a malformed entry keeps its error outside cache mode
Same test file as the enterprise tree, so the next sync sees one version.
