redis_scan now maps ASCII case variants of json to the native RedisJSON type ReJSON-RL in its SCAN TYPE argument. Other type strings retain their bytes, and the output keeps the caller's original type label. The tool and field descriptions document both spellings.

Bounded coverage for #1218; leaves #1218 open. Schema, defaults, read-only annotations and traversal are unchanged. A non-checkout merge-tree check is clean against #1325 at 718c99c and retains both changes; that contributor branch is unchanged, and no combined runtime result is claimed.

Validation:

• Same alias test corpus: old handler 3 passed / 3 failed; updated handler 6 passed.
• Minimal and all-feature configurations: 6 alias tests plus 2 existing limit-guard tests passed; none ignored or filtered out.
• Pinned Redis 8.6.7 / RedisJSON 80600: JSON aliases and native type return the same JSON keys under RESP2 and RESP3, with string/unfiltered controls and stored values checked.
• Targeted catalog baseline contract, formatting and strict all-target/all-feature Clippy pass.

Cargo.lock is unchanged. The PR remains in draft for independent review, the separate security dependency update and hosted validation after refresh.
