Summary as of 7d678de

Initial implementation of sil-lift, a Python library for LIFT (Lexicon Interchange Format) 0.13. The library provides:

• Full object model: 35+ typed dataclasses for all LIFT 0.13 elements
• Byte-fidelity passthrough: load() → save() with no edits is byte-identical; untouched entries keep their exact source bytes even when siblings change
• Streaming: open_reader() / open_writer() for O(one-entry) memory
• Validation: RELAX NG + ranges schema + semantic checks
• Canonical sort: LiftSorter-informed, locale-independent
• CLI: validate / stats / sort / check-media / export
• Zip packages: read/write zipped LIFT folders

Architectural highlights:

• Out-of-schema content (unknown elements, attributes, comments) is carried losslessly in Extras buckets
• Passthrough uses a raw-byte scanner (_scan.py) to locate entry spans, then SHA-256 digests to detect changes
• Validation is always explicit (never on load/save)
• Only runtime dependency: lxml; Python 3.11+
• Public API is exactly sil_lift/__init__.py's __all__; no lxml types leak into public annotations
