chore: remove dead helpers in dspy/propose/utils

[detail-app]

Remove three unused top-level functions from dspy/propose/utils.py: create_instruction_set_history_string, parse_list_of_instructions, and get_program_instruction_set_string. Also drop the now-unneeded "import json" that only parse_list_of_instructions used.

These functions had no production callers, no test references, and were not re-exported in dspy/propose/init.py. They were added in the initial MIPRO release commit and never wired up; get_program_instruction_set_string was only called by the dead create_instruction_set_history_string. A repo-wide search confirms no imports or call sites.

Greptile Summary

This PR removes three isolated, unused instruction-history helpers from dspy/propose/utils.py and drops their now-unused json import.

• Preserves all currently referenced proposal utilities.
• Does not alter the exported dspy.propose API.
• Leaves no remaining references to the removed helpers.

Confidence Score: 5/5

The PR appears safe to merge because it only removes isolated dead code with no tracked callers or public exports.

No actionable failures remain; repository references and package exports confirm that the deleted helpers and import were unused.
