chore: track pipelex keyword-only refactor + migrate to PipelexMTHDSProtocol

[lchoquel]

What

Pins cocode to the pipelex keyword-only-arguments refactor branch (refactor/Function-calling-4) to validate it in lockstep, and migrates the SWE runner off the removed PipelexRunner class.

Changes

• pyproject.toml / uv.lock: pipelex ==0.32.1 → ==0.33.0 via a temporary [tool.uv.sources] git pin at rev 529b9082.
• cocode/swe/swe_cmd.py (production) + tests/integration/test_hello_world.py: PipelexRunner → PipelexMTHDSProtocol, execute_pipeline() → execute(). response.pipe_output is unchanged.
• CHANGELOG.md: [Unreleased] entry.

Why the runner rename is here

The pinned PyPI pipelex (0.32.1) still had PipelexRunner. Pinning to the branch (which tracks pipelex dev) surfaces the already-landed runner rename — the runner is now the MTHDS Protocol implementation (PipelexRunner removed, execute_pipeline→execute) — in addition to the keyword-only work, so cocode needs the rename to keep building.

Verification

Local, all green: make agent-check, make agent-test, uv lock --check.

Note

The git-rev pin is temporary — swap it back to a released pipelex version once the keyword-only refactor lands on PyPI.

Summary by cubic

Tracks the pipelex keyword-only-arguments refactor and migrates the SWE runner to PipelexMTHDSProtocol. Moves from a temporary git pin to the released pipelex 0.37.0 and cleans up configs/docs to match the new protocol.

• Refactors

  • Replace PipelexRunner with PipelexMTHDSProtocol and execute_pipeline() with execute() in cocode/swe/swe_cmd.py and the hello‑world test; response.pipe_output unchanged.
  • Remove experimental flags from pipelex configs; drop deprecated combined_output in *.mthds, normalize the changelog template, and rename TestingStrategyDoc→TestStrategyDoc (field testing_strategy→test_strategy) in SWE docs.

• Dependencies

  • Use pipelex 0.37.0 from PyPI (keyword‑only non‑subject params); removed the temporary local/git pin. Call sites already pass affected args by keyword.
  • Pin ruff to 0.14.13; lockfile updated.

Greptile Summary

This PR updates cocode for the newer Pipelex runner API and temporary dependency pin. The main changes are:

• Pins pipelex to 0.33.0 with a temporary uv git source.
• Replaces PipelexRunner.execute_pipeline() with PipelexMTHDSProtocol.execute() in the SWE runner helper.
• Updates the hello-world integration test for the renamed runner API.
• Adds an unreleased changelog note for the Pipelex refactor tracking.

Confidence Score: 5/5

This looks safe to merge.

• No blocking issues found in the changed code.
• The updated runner call preserves the response.pipe_output contract used by existing callers.
• The changed Pipelex calls use keyword arguments where the new API requires them.
