chore(utils): remove unused dummy_rm helper

[detail-app]

Removes the ''dummy_rm'' retrieval-manager helper and its re-export from ''dspy.utils''. The function had zero callers anywhere (no production, test, or doc usage); its only consumers (legacy ''tests/dsp_LM/'' and ''tests/functional/'' suites) were deliberately removed in the V2.6 RC-01 deprecations (stanfordnlp#1936), leaving it a left-over utility with no live feature.

Greptile Summary

Removes the unused dummy_rm retrieval helper and its re-export from dspy.utils.

• Deletes the helper implementation from dspy.utils.dummies.
• Removes the symbol from the package import surface and __all__.
• The implementation is unused internally, but removing the released public export introduces an immediate downstream compatibility break.

Confidence Score: 4/5

The PR is not yet safe to merge because existing consumers of the exported helper will encounter an immediate import failure.

The implementation itself is internally unused and cleanly removable, but deleting an explicitly exported 3.x API symbol without a deprecation shim creates a concrete downstream compatibility failure.

Public API removed abruptly

Removing dummy_rm from this explicit public export without a deprecation period breaks downstream code that imports it from dspy.utils. Those applications will fail during import after upgrading, even though the package remains on version 3.3.1. Preserve a compatibility shim with a deprecation warning until the intended removal version.
