Follow-up to apache#635: TableId, PartitionId, and BucketId already have aliases in lib.rs, but snapshot_id was still spelled i64 everywhere. Add a matching SnapshotId alias and apply it to the hand-written sites: LakeSnapshot, LakeSnapshotInfo, KvSnapshot, KvSnapshotLeaseForBucket, the admin client methods, and the get_kv_snapshot_metadata / get_lake_snapshot request constructors.

Purpose
Linked issue: close #636
TableId,PartitionId, andBucketIdalready have type aliases inlib.rs(extended to the write path in #635), butsnapshot_idwas still spelledi64everywhere. This adds a matchingSnapshotIdalias so snapshot-related signatures read consistently with the other ID types.Brief change log
pub type SnapshotId = i64;next to the existing aliases inlib.rs.LakeSnapshot(metadata/table.rs),LakeSnapshotInfo,KvSnapshot,KvSnapshotLeaseForBucket, the admin client methods (get_kv_snapshot_metadata,get_lake_snapshot), and theGetKvSnapshotMetadataRequest/GetLakeSnapshotRequestconstructors.HashMap<TableBucket, i64>offset values stayi64since they are offsets, not snapshot IDs.Tests
No behavior change (the alias resolves to the same type).
cargo test --workspace: 576 passed, 0 failed.cargo clippy --workspace --all-targetsandcargo fmt --all --checkare clean.API and Format
Public signatures now name
SnapshotIdinstead ofi64; since it is a plain type alias, this is source- and ABI-compatible. No storage format impact.Documentation
No new feature; no documentation changes needed.
