The previous __-joined scheme was not injective: a directory named
a__b and a nested path a/b both mapped to the same ID. Use a sha256
hash suffix of the resolved path instead, which is collision-free
and keeps the dir name as a human-readable prefix.
Added regression test for separator collision case.
workflow_dir.name was used as the discovery key and API ID, so two
different WORKFLOW_ROOTS containing a leaf directory with the same
name would silently drop one. Use root name + relative path joined
with __ as a stable unique ID instead.

- Add resolve() + is_relative_to() check in _extract_zip() to block
nested traversal entries like nested/../../escape.txt
- Sanitize server-provided skill name in import_skill() to prevent
directory escape via malicious record metadata
- Add 6 regression tests covering both attack vectors
Closes#17
