fix: stop reasoning-only loops for GLM/minimax

[marius-kilocode]

Problem

Some models (reported with z-ai/glm-4.7:free and minimax/minimax-m2.1:free) can stream only reasoning (<think>/reasoning deltas) and finish the step with finish: \"unknown\". SessionPrompt.loop keeps looping on unknown, causing an infinite repetition.

Original issue: Kilo-Org/kilocode#6333

Fix

• Add a dedicated MessageReasoningStuckError.
• In SessionProcessor, track whether a step produced any non-reasoning output (text/tool parts).
• If a step is reasoning-only and exceeds a threshold (or finishes with unknown), mark the message with MessageReasoningStuckError and stop the loop.
• Format the error nicely in the CLI.

Tests

• bun run typecheck
• bun test (packages/opencode)

Closes Kilo-Org/kilocode#6333

Hi! Thank you for taking the time to contribute to this project—we really appreciate it. 🙏

We are currently working on re-platforming the core of our VS Code and JetBrains extensions to be based on our new Kilo CLI, with a complete rebuild based on OpenCode as our new foundation, and the moment has come to promote this repository to become the main repository. To do that, we moved the code from this repository to the kilocode repository.

This unfortunately means we cannot merge this branch here anymore. Please add https://github.com/Kilo-Org/kilocode.git as a remote, and push your branch there and create a new PR in https://github.com/Kilo-Org/kilocode . We unfortunately cannot do this for you as then the PR would not be in your name anymore. If you need any help, feel free to ask on our Discord in #kilo-dev-contributors

Sorry for the inconvenience and thank you for contributing to Kilo!
