### New Features
- Typed `tool_call` handler return values via `ToolCallEventResult` exports from the top-level package and core extension entry. See [docs/extensions.md](docs/extensions.md).
- Updated default models for `zai`, `cerebras`, `minimax`, and `minimax-cn`, and aligned MiniMax catalog coverage and limits with the current provider lineup. See [docs/models.md](docs/models.md) and [docs/providers.md](docs/providers.md).
### Added
- Added `ToolCallEventResult` to the `@mariozechner/pi-coding-agent` top-level and core extension exports so extension authors can type explicit `tool_call` handler return values ([#2458](https://github.com/badlogic/pi-mono/issues/2458))
### Changed
- Changed the default models for `zai`, `cerebras`, `minimax`, and `minimax-cn` to match the current provider lineup, and added missing `MiniMax-M2.1-highspeed` model entries with normalized MiniMax context limits ([#2445](https://github.com/badlogic/pi-mono/pull/2445) by [@1500256797](https://github.com/1500256797))
### Fixed
- Fixed `ctrl+z` suspend and `fg` resume reliability by keeping the process alive until the `SIGCONT` handler restores the TUI, avoiding immediate process exit in environments with no other live event-loop handles ([#2454](https://github.com/badlogic/pi-mono/issues/2454))
- Fixed `createAgentSession({ agentDir })` to derive the default persisted session path from the provided `agentDir`, keeping session storage aligned with settings, auth, models, and resource loading ([#2457](https://github.com/badlogic/pi-mono/issues/2457))
- Fixed shared keybinding resolution to stop user overrides from evicting unrelated default shortcuts such as selector confirm and editor cursor keys ([#2455](https://github.com/badlogic/pi-mono/issues/2455))
- Fixed Termux software keyboard height changes from forcing full-screen redraws and replaying TUI history on every toggle ([#2467](https://github.com/badlogic/pi-mono/issues/2467))
- Fixed project-local npm package updates to install npm `latest` instead of reusing stale saved dependency ranges, and added `Did you mean ...?` suggestions when `pi update <source>` omits the configured npm or git source prefix ([#2459](https://github.com/badlogic/pi-mono/issues/2459))
