### Breaking Changes
- Raised the minimum supported Node.js version to 22.19.0.
### Fixed
- Fixed compaction summary calls to use custom agent stream functions, preserving proxy-backed LLM routing ([#4484](https://github.com/earendil-works/pi/issues/4484)).
- Fixed system prompt and context file boundaries to use explicit XML tags instead of Markdown headings, reducing inconsistent boundary ingestion by models ([#4541](https://github.com/earendil-works/pi/pull/4541) by [@herrnel](https://github.com/herrnel)).
- Fixed OpenAI Codex generated model metadata to use the current upstream model list inherited from `@earendil-works/pi-ai` ([#4603](https://github.com/earendil-works/pi/pull/4603) by [@mattiacerutti](https://github.com/mattiacerutti)).
- Fixed GitHub Copilot GPT model thinking metadata inherited from `@earendil-works/pi-ai` to map unsupported minimal thinking to low ([#4622](https://github.com/earendil-works/pi/pull/4622) by [@mattiacerutti](https://github.com/mattiacerutti)).
- Fixed user-scoped npm pi packages to install under `~/.pi/agent/npm/` instead of npm's global package root, avoiding permission errors with system-managed Node installs ([#4587](https://github.com/earendil-works/pi/issues/4587)).
- Fixed Mistral requests failing after the global fetch proxy/timeout workaround by removing the custom fetch override and using undici 8 dispatcher support instead ([#4619](https://github.com/earendil-works/pi/issues/4619)).
- Fixed default output token requests for models whose advertised output limit is effectively their full context window, avoiding impossible provider requests inherited from `@earendil-works/pi-ai` ([#4614](https://github.com/earendil-works/pi/issues/4614)).
