v5.3.0

⚠️ Breaking change — JSON wire format

Operation.From (json "f") now carries the source path for OpMove/OpCopy. Previously the source path was stored in Operation.Old (json "o"). Patches serialised by v5.2.0 and earlier will not round-trip cleanly through ParseJSONPatch / UnmarshalJSON. Generated *_deep.go files are unaffected — Move/Copy ops fall through to the reflection path which now reads From.

Migration: re-serialise any persisted patches, or attach a transformation step that copies the source path from Old to From for OpMove/OpCopy ops before parsing.

What's Changed

Twelve correctness/robustness fixes plus the wire-format split, all in #45:

• engine: OpCopy deep-copies the source so reference-typed destinations no longer alias.
• selector: MapKey RFC 6901-escapes the key so values containing / or ~ navigate correctly.
• patch: Reverse drops OpLog ops instead of emitting a malformed zero-Kind operation.
• patch: ParseJSONPatch only lifts the leading test-op into Guard; a later same-shape entry no longer overwrites it.
• operation: split From (source path) from Old (prior value) — see the breaking change note above.
• deep-gen: root-level strict check uses a comma-ok type assertion (no more panic on mismatched Old).
• engine: ApplyOpReflectionValue nil-checks the logger.
• engine: OpMove/OpCopy from a non-existent source now surface an error (test gap closed).
• hlc: Clock.SetLatest rehydrates the clock under the mutex; CRDT.UnmarshalJSON uses it.
• hlc: Clock.Reserve panics on negative n or int32 overflow instead of silently wrapping.
• condition: Not with an empty Sub returns an explicit error.
• crdt: Set.Len no longer materialises the full Items() slice.
