upgrade conductor core to v0.5.0

[laceyp99]

Summary

• upgrade the locked conductor-core dependency from v0.4.0 to v0.5.0
• retain Eval's public LoopGenerationEngine integration after auditing v0.5.0 removals and stricter request contracts
• make zip() truncation behavior explicit in analysis chart data to satisfy Ruff's B905 rule without changing output

Testing

• uv sync --locked --all-extras - passed
• uv run --locked --all-extras ruff format --check . - passed
• uv run --locked --all-extras ruff check . - passed
• uv run --locked --all-extras pytest -q - passed (130 tests)
• uv build - passed

Notes

• No paid provider evaluations were run. Validation used deterministic tests and package builds.
• The v0.5.0 removal audit found no Eval usage of legacy Gemini _G models, string-timing helpers, times_as_string, Ollama force_refresh, or the private routing return switch.

Looks good to merge! Pretty easy migration. Also manually tested the new models within the arpeggiator test eval script and all of the models are +95% accuracy.

I need to update the test eval to refocus to chord progressions in efforts of making the eval harder. Also, in step, I'd want to update the analysis to better reflect insights for chord progressions. I'll create an enhancement issue to the repo next.
