Subject: [PATCH] ci: clear cargo registry cache before workspace publish
 dry-run

The workspace publish dry-run fails with `unresolved import
miden_utils_sync::OnceLockCompat` during verification. This happens
because cached registry data from previous CI runs can interfere with
cargo's temp registry used for workspace dependency resolution.

During verification, cargo should use the packaged v0.21.0 from the
temp registry, but stale cache entries may cause it to resolve
against crates.io data instead (where v0.20.1 lacks OnceLockCompat).

Clear ~/.cargo/registry/{cache,index,src} before the dry-run to ensure
fresh resolution without interference from cached data.

Closes #2505
