Acceptance Criteria

• All Stackable crates use edition = "2024" in their Cargo.toml
• CI passes

Expected effort: 1-2 days total across all repos. If a specific repo turns out to be a rabbit hole, open a separate issue for it and move on.

Out of scope: any actual code refactoring beyond what's needed for edition compatibility
