Make a leading **/ in an exclude pattern match at the top level (closes #303)

An unanchored exclude pattern such as **/node_modules or **/*.pyc
needed a / before the name, so it excluded sub/node_modules and
sub/y.pyc but backed up node_modules/ and x.pyc directly under the
snapshot path. An unanchored pattern already matches at every depth,
so the leading **/ is now dropped when the pattern is compiled and,
as in gitignore, the pattern matches the top level too.

Judgement call: an anchored /**/x is left as it was; the issue covers
patterns that start with **/.

Model: opus-5-5

 # Completed Steps
 
-- 2026-10-13: Recorded the size of the stored object for a blob a backup
-  found already stored
-  ([issue #300](https://git.eeqj.de/sneak/vaultik/issues/300)). When the
-  upload was skipped, the blob row and the manifest kept the size of the
-  local copy, which differs from the stored object's when
-  `compression_level` or the recipients changed since it was written.
-  `snapshot verify` then failed on a good snapshot, shallow and deep,
-  and the listed sizes were wrong. Marking the blob uploaded now records
-  the size of the object in storage.
-
-- 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: Made an exclude pattern starting with `**/` also match
+  directly under the snapshot path
+  ([issue #303](https://git.eeqj.de/sneak/vaultik/issues/303)).
+  `**/node_modules` and `**/*.pyc`, the patterns `config.example.yml`
+  uses, excluded `sub/node_modules` and `sub/y.pyc` but backed up
+  `node_modules/` and `x.pyc` at the top of the path, since the pattern
+  required a `/` before the name. As in gitignore, such a pattern now
+  matches at every depth, the top included.
 
 - 2026-10-12: Bound the local index to the destination an `s3.*` config
   names ([issue #298](https://git.eeqj.de/sneak/vaultik/issues/298)).
