v0.11.0 — Surgical Serialization

[0.11.0] - 2026-08-02

Added

• Surgical Serialization — byte-level source span tracking on every AST node; segment-based splice — edits regenerate only the touched region, untouched text is byte-copied
• proptest fidelity property tests (new dev-dependency)
• 10MB edit-flush benchmarks (divan)

Changed

• lush_source now splices segments; falls back to full serialization for flow-style regions, non-default layout documents, merged keys, CRLF/BOM documents, and after materialization (single-burst model)
• Splice edits preserve ---/.../directive marker lines as untouched bytes (full serialization previously dropped them — deliberate behavior difference)
