Greptile Summary

Adds an advisory warning (WARN_AUBE_OVERRIDE_DOLLAR_REF_DEPRECATED) for pnpm's deprecated $-prefixed version reference syntax in overrides entries, without changing any resolution or drop behavior. The warning fires after overrides are merged but before resolve_override_refs, so the existing WARN_AUBE_OVERRIDE_MISSING_DEP path continues to run unaffected.

• New deprecated_dollar_override_refs helper filters merged overrides for $-prefixed values (excluding bare $), returning (key, dep) pairs used to emit the structured warning via tracing::warn!.
• The code constant is registered in aube-codes following the project convention, and docs/error-codes.data.json is regenerated so the VitePress docs page picks it up automatically.
• A unit test covers the positive case, the non-$ case, and the bare-$ exclusion.

Confidence Score: 5/5

Safe to merge; the change is purely advisory and touches no resolution or mutation logic.

The warning is emitted on a read-only pass over the already-merged overrides map and does not alter any data structure, drop behavior, or resolver inputs. The helper function is small and covered by a unit test that exercises the three important cases. All project conventions (error-code registration, tracing emit pattern, docs regeneration) are followed correctly.

No files require special attention.
