v1.3.0

New APIs

• diffWithCovers(old, new, covers, options) — create standard hdiffpatch payloads from caller-provided cover lines, with replace / merge / native-coalesce modes and optional debugCovers introspection
• patchSingleStream(oldPath, diffPath, outNewPath[, cb]) — file-level apply for single-compressed diffs produced by diff() / diffWithCovers()

CLI

• hdp patch now auto-detects the diff format by header magic (HDIFF13 / HDIFFSF20), so it can apply both hdp diff output and diff() / diffWithCovers() output

Platforms & packaging

• New prebuilds: darwin-x64 and win32-x64 (in addition to darwin-arm64, linux-x64, linux-arm64)
• Robust native module loading: local dev build → per-platform prebuild → node-gyp-build fallback with a clear error on unsupported platforms
• Prebuilds-only install: the install script was removed (the published package ships no sources); engines.node >= 14.17 declared
• npm publish now includes provenance attestation

Hardening & tests

• Diff-declared sizes are validated before allocation (size_t truncation guard)
• Cover fields reject negative numeric strings ("-1" no longer wraps to UINT64_MAX)
• CI test matrix across 5 platforms under both Node and Bun runtimes; async callback paths, corrupt-diff error propagation, and CLI formats are now covered
