The native wheel returns a record id inside a row as its own RID class; the JVM wheel returns the engine's RID. This PR makes the native class substitutable for the Java one in the places user code touches it, so a record id behaves the same on both wheels. The contract is written in docs/api/results.md under "Record ids in rows" (same text as the JVM PR, which carries the tests and docs for main): a record id in a row is an RID object, str(rid) is the text, equal RIDs hash alike, RIDs sort by bucket and position, getBucketId(), getPosition(), toString() and isValid() work, and it goes back in as a parameter and to lookup_by_rid().

What changes in _native/codec.py: RID gets ordering (<, <=, >, >=, by bucket then position, only against another RID) and the Java methods getBucketId, getPosition, toString, isValid, equals, compareTo. It still equals its own text and hashes like it, which the Java RID does not; the docs say to compare str(rid) and not to rely on either. What changes in _native/database.py: Result.get_rid() returns the identity of a row that projects @rid without an alias (SELECT @rid, name FROM T), as the JVM wheel does; it was None. Python only, no image rebuild.

Stacking and overlap with the open native PRs: none needs to merge first. The branch is on native-preview (91a6ad7). Files shared with open PRs are _native/database.py (#514, #521, #522, #525, #526) and _native/codec.py (#525); I merged each of those heads into this branch with git merge-tree and none conflicts. #520 and #523 do not touch my files.

Local checks: tests/test_record_id_values.py 12 passed on the native wheel (3 of them failed before this change: sorting, getBucketId, get_rid() of a projected @rid), run with ARCADEDB_BACKEND=native against an existing image (the #521 nnext image, no rebuild); with test_core.py, test_resultset.py, test_graph_api.py, test_vector.py, test_docs_examples.py the total is 127 passed, 24 skipped (the usual not-yet-native skips, no failures); pre-commit hooks passed. Not run: the full suite, the JVM wheel against this branch, CI.

Closing here: the bindings moved to ArcadeData/arcadedb-python, and this change is merged there with the native port, ArcadeData/arcadedb-python#66 (commit 9ae92b3: the Java RID surface on the native RID, and Result.get_rid() for a projected @rid). The branch stays.
