Description
Goal
Make the centralized Stable selector and default dataset writes resolve to Lance file format 2.2, the current stable format.
Context
Implementation: https://github.com/lance-format/lance/pull/8657
The release policy and enum default currently resolve Stable to 2.1 even though 2.2 is the intended stable format. Lance 2.3 remains the next unstable format.
Completion gates
- https://github.com/lance-format/lance/pull/8657 is reviewed and merged.
- Rust selector/default behavior and Java integration expectations agree on 2.2.
- Existing exact-version selectors and persisted exact identities remain unchanged.
