Refuse a relative file:// storage_url and decode its escapes (closes #299 )

The path after file:// was used as written. file://dest resolved against the working directory, so a backup run from another directory wrote elsewhere, exited 0 and left a snapshot that could not be restored; my%20stick created a directory with that literal name. Config load now refuses a file:// storage_url whose path is not absolute. ParseStorageURL refuses it too and decodes percent-escapes; a literal space still works. The rule is written in both packages because config cannot import storage, which imports config. A % not followed by two hex digits now fails when the storage is opened, not at config load. Model: opus-5-5

 # Completed Steps

- 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.
+- 2026-10-13: Refused a `file://` `storage_url` whose path is relative
+  ([issue #299](https://git.eeqj.de/sneak/vaultik/issues/299)). The text
+  after `file://` was used as written, so `file://dest` resolved against
+  the working directory: a backup run from another directory wrote to a
+  different destination, still exited 0, and left a snapshot that could
+  not be restored. Such a URL now fails when the config loads, with an
+  error asking for an absolute path. Percent-escapes in the path are now
+  decoded, so `my%20stick` names the directory `my stick` instead of
+  creating one named `my%20stick`; a path written with a literal space
+  works as before.
