[I] Support rowkind.field for CDC-style writes on deduplicate PK tables [paimon-rust]

["Pandas886 (via GitHub)" <gi...@apache.org>]

Pandas886 opened a new issue, #502:
URL: https://github.com/apache/paimon-rust/issues/502

   ### Describe the feature
   
   I'd like to write changelog-style rows into a primary-key table by putting the row kind (`+I` / `-U` / `+U` / `-D`) in a user column, matching Java's `rowkind.field` option.
   
   Today the Rust write path fails loud with something like "KeyValueFileWriter does not support rowkind.field", even though the option can already be parsed.
   
   ### Motivation
   
   This is useful for CDC / ETL pipelines that already carry a short string op column and don't want to invent a separate `_VALUE_KIND` convention on the client side.
   
   ### Proposed scope
   
   - Parse short-string row kinds (`+I`, `-U`, `+U`, `-D`)
   - Honor `rowkind.field` on **deduplicate** PK tables only
   - Validate the configured field (exists, STRING, not conflicting with system columns)
   - Support `ignore-delete` / `ignore-update-before` filtering when writing
   - Integration tests aligned with the Java ITCase scenarios I could map over
   
   Out of scope for this issue: other merge engines, lookup/compact, DataFusion SQL surface.
   
   ### Additional context
   
   Happy to send a PR if this direction looks good.
