Keep the progress line of a multi-path snapshot within 100% (closes #271)

One progress reporter spans every path of a snapshot. Its counts of
files and bytes processed run across all the paths, while the totals
they were divided by were reset to each path's own, so a second path
smaller than the first showed more than 100% and an ETA of `unknown`.
The totals now add up over the paths scanned so far. The rate behind
the ETA restarts when each path's scan phase ends, so that phase does
not lower the rate while the path is processed; until then the rate is
the previous path's. SetTotalSize is renamed AddTotalSize because it
now adds.

The issue says the ETA went negative; it was computed negative and
printed as `unknown`.

 # Completed Steps
 
-- 2026-10-13: Stopped `remote info` counting a file under `blobs/` that
-  is not a blob as an orphaned blob
-  ([issue #295](https://git.eeqj.de/sneak/vaultik/issues/295)). A stray
-  file such as `.DS_Store` was reported as an orphaned blob and the
-  report advised running `prune`, which skips such a file and deleted
-  nothing. `remote info` now takes its blob list from the same listing
-  `prune` uses, in the table and in `--json`.
-
-- 2026-10-13: Made `snapshot remove` fail for a snapshot that does not
-  exist ([issue #293](https://git.eeqj.de/sneak/vaultik/issues/293)).
-  The command never checked the ID: it reported the snapshot removed
-  from the local database and from the destination store and exited 0,
-  under `--json`, `--dry-run` and `--local-only` too. An ID that names
-  no snapshot in the local index or on the destination store is now an
-  error; with `--local-only`, the snapshot must be in the local index.
-  The command now reports a removal from either side only when one
-  happened, and `remote_removed` is true only when metadata was deleted.
-
-- 2026-10-12: Bound the local index to the destination an `s3.*` config
-  names ([issue #298](https://git.eeqj.de/sneak/vaultik/issues/298)).
-  Only `storage_url` was checked, so after `s3.bucket` or `s3.prefix`
-  changed, the next backup treated every chunk as already stored,
-  uploaded nothing, and completed a snapshot that could not be restored.
-  Without `storage_url`, the local index is now bound to `s3.endpoint`,
-  `s3.bucket` and `s3.prefix`, and a change is refused as a changed
-  `storage_url` is.
-
-- 2026-10-12: Rejected a retention duration longer than about 292 years
-  ([issue #289](https://git.eeqj.de/sneak/vaultik/issues/289)). The
-  number given to `--older-than` or `--keep-newer-than` was multiplied
-  by the length of its unit with no limit, so from `293y`, `15251w`,
-  `3559mo` or `106752d`, or a sum of parts such as `200y200y`, the
-  result wrapped to a negative duration. The cutoff then lay in the
-  future, every snapshot of the name was deleted, the one just made
-  included, and the command exited 0. Such a duration is now rejected
-  as invalid and nothing is deleted.
-
-- 2026-10-08: Made a backup cancelled under `--skip-errors` stop at once
-  ([issue #286](https://git.eeqj.de/sneak/vaultik/issues/286)). After
-  Ctrl-C or SIGTERM, phase 2 treated the cancellation error from each
-  remaining file like an unreadable file: it opened the file, printed an
-  error line for it, counted it as failed and went on to the next one.
-  The run now stops at the first file after the cancellation, and no
-  file is counted as failed because of it.
-
-- 2026-10-08: Made `remote nuke` delete the `.partial` files that
-  uploads cut off part-way leave on the destination store
-  ([issue #281](https://git.eeqj.de/sneak/vaultik/issues/281)). The
-  file and rclone listings skip such a file, so the command left it in
-  place and still reported the store empty. It now removes them under
-  `metadata/` and `blobs/` as its last step.
-
-- 2026-10-08: Made a local index error while recording a directory or
-  symlink stop a backup under `--skip-errors`
-  ([issue #284](https://git.eeqj.de/sneak/vaultik/issues/284)). Phase 2
-  only records such an entry in the local index, since it has no data
-  to open or read, but an error doing so was skipped like an unreadable
-  file. The snapshot then completed without the entry, and a restore
-  did not recreate it. The error now stops the backup, as it does
-  without the flag.
-
-- 2026-10-08: Counted a file that a backup could not store as failed
-  ([issue #280](https://git.eeqj.de/sneak/vaultik/issues/280)). A file
-  that phase 1 counted and phase 2 could not open, because it was
-  unreadable under `--skip-errors` or removed in between, was reported
-  in the summary as unchanged with its bytes as backed up, and the
-  `snapshots` row's `file_count` and `total_size` included it. The
-  summary now counts it as failed, and its data total and the row leave
-  it out.
-
-- 2026-10-08: Made `remote info` report a snapshot's blob count and
-  blob size as unknown when its manifest cannot be read
-  ([issue #272](https://git.eeqj.de/sneak/vaultik/issues/272)). The
-  orphan figures were already unknown in that case, but the snapshot's
-  row still gave 0 blobs and 0 B, in the table and in `--json`. The row
-  now reads `unknown` and `--json` gives `null`. A directory with no
-  manifest still shows 0, since the orphan figures count its blobs as
-  orphaned.
