Bug Fixes

Fix: Non-ASCII characters in DataHub write operations (#61)

Fixed ingestProposal validation failures when writing metadata containing non-ASCII Unicode characters such as em dash (—), en dash (–), bullets (•), or CJK characters.

Root cause: DataHub's GenericAspect.value is typed as bytes in the RestLi PDL schema, which uses Avro-style encoding permitting only characters U+0000–U+00FF. Go's json.Marshal produces raw UTF-8 multi-byte sequences for characters above this range, causing RestLi to reject the request with HTTP 400 before the handler executes.

Fix: Added escapeNonASCII() to convert non-ASCII runes to \uXXXX JSON escape sequences in the inner aspect JSON before embedding in the GenericAspect.value string. Includes a fast path that skips allocation entirely for pure-ASCII content (zero overhead for the common case). Supplementary characters (U+10000+) are encoded as surrogate pairs.

Affected operations: UpdateDescription, UpdateColumnDescription, AddTag, AddGlossaryTerm, AddLink — any write where the aspect content contains characters above U+00FF.
