Replace `[lints] workspace = true` with explicit lint configuration in
each crate's Cargo.toml. This allows nix-cargo-integration to build
individual crates in isolation, as it cannot resolve workspace-level
lint configuration when building crates independently.
Pre-release versions (2.33.0pre) now enable 2.33 APIs, allowing development
and integration testing before the stable release. Tests remain disabled for
2.33 until stable to avoid blocking on unrelated pre-release issues.
