Prepare selective patch releases

[mizchi]

Summary

• add independent patch / minor release preparation for modules changed since the previous release
• keep publish ordering and the --apply safety gate while syncing npm and CLI metadata only when mizchi/bit changes
• migrate deprecated MoonBit default, debug representation, hash, and map APIs
• prepare patch versions for the 14 touched modules (mizchi/bit and mizchi/bitx_hub at 0.46.1; the other affected modules at 0.45.7)

Why

The workspace release helper previously assumed lockstep versions and the current MoonBit toolchain emitted 121 source deprecation warnings plus four warnings from the release helper. Independent version preparation avoids republishing unchanged modules, while the API migrations keep all supported targets warning-free.

Impact

Release preparation now updates only changed package manifests, preserves topological publishing, refuses unsafe dirty-worktree publishing, and keeps the installable npm/CLI version synchronized with mizchi/bit.
