Fix unused clippy lint
The `opcodes` module is only used by script which is feature gated on
`alloc`. This causes an unused lint error on `no-default-features`.
Feature gate the whole module on `alloc`.
What changed, and why it matters
This is a minor build hygiene fix. A Rust module that was only used behind an optional feature was triggering a compiler warning when that feature was disabled. The change simply hides the module unless the relevant feature is enabled, silencing the warning. There is no security relevance.
No security action required. Treat as normal maintenance.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The commit adds #[cfg(feature = "alloc")] to the opcodes module in primitives/src/lib.rs. The module is only used by script, which itself is gated on the alloc feature. Without this guard, building with --no-default-features produced an unused-module lint. The change is purely conditional compilation to satisfy clippy and has no functional or security impact.
