clawbot 4193ced1f6 Report blobs shallow verify could not check apart from missing ones (closes #318)
check / check (push) Waiting to run
Shallow snapshot verify counted every error from checking a blob or the
encrypted database as "missing" and printed the error nowhere, so a
permission error or an S3 403 read as data loss. Now only a not-found
answer from storage counts as missing. Any other error is reported as
could not be checked, with the error storage returned, in the text
report and under --json (the new unchecked list and
database_check_error field), and the run fails. Under --quiet, which
drops the report, each of those errors is logged as a warning on
stderr.

The database check moved into its own small function because the verify
function was at the linter's length limit.

clawbot 34f61fb408 Make remote nuke delete leftover .partial uploads (closes #281)
check / check (push) Canceled after 0s
The file and rclone listings skip an object whose name ends in
`.partial`, the temporary name a `file://` or rclone upload writes
before moving the object into place. `remote nuke` deletes only what
the listings return, so it left the `.partial` objects killed uploads
leave behind and still reported the destination store empty.

Storer gains DeletePartialUploads. The file and rclone backends remove
every `.partial` object under the prefix; S3 has none to remove, since
it shows an object only once its upload completes. `remote nuke` calls
it for `metadata/` and `blobs/` as its last step.

Empty directories under a `file://` destination are still left behind.

clawbot 82c51a5337 Validate blob hashes, offsets and lengths from the destination (closes #155)
check / check (pull_request) Successful in 1m22s
check / check (push) Successful in 3m30s
A blob hash read back from the downloaded snapshot database or the store listing was trusted unchecked. A hostile remote could set a hash such as "aa/../../etc" and have a decrypted blob written outside the cache directory, or feed a short or negative value that panicked a command.

blobDiskCache.path now refuses any key with a path separator, and ReadAt rejects a negative offset or length, bounding so a sum cannot overflow past the check. A new isBlobHash helper gates FetchBlob, shallow and deep verify, and restore: buildBlobIndexes rejects every hash from the snapshot database before any fetch. The blobs/ and metadata/ listings skip a non-conforming name, and short-hash prefixes in log and error text go through a panic-safe shortHash helper.
