[I] Batch incremental scan: read existing changelog manifests + AuditLogTable [paimon-rust]

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

Pandas886 opened a new issue, #504:
URL: https://github.com/apache/paimon-rust/issues/504

   ### Describe the feature
   
   Extend the batch incremental scan API to read **existing** changelog files from snapshots (`changelog_manifest_list`), and expose an `AuditLogTable`-style read that surfaces row kinds as `+I` / `-U` / `+U` / `-D`.
   
   ### Motivation
   
   Tables written with `changelog-producer=input` (and other producers that already materialize changelog files) should be readable incrementally without generating changelog on the Rust side.
   
   ### Proposed scope
   
   - Changelog planning over snapshots in `(start, end]`
   - Skip OVERWRITE / missing changelog lists cleanly
   - `AuditLogTable` (or equivalent) with `rowkind` as the first column
   - Tests with input-changelog fixtures (no compact/lookup generation in this PR)
   
   Depends on the Delta/Auto incremental API landing first.
   
   ### Out of scope
   
   - Generating lookup/compact changelogs in Rust
   - Diff mode (derive changelog by comparing before/after images)
