Extracts canonical path-parsing and packet-hashing logic from
modules/utils.py into shared/parsers/path_parser.py and
shared/parsers/packet_parser.py, eliminating duplication across
three prior implementations. All callers updated to import from
shared.parsers.*; modules/utils.py re-exports via shared imports
for any remaining internal callers. 2866 tests pass.
