- Introduced `Max` as a first-class reasoning effort tier across all packages, including AI providers, coding agent configurations, and RPC protocols.
- Refactored model effort ladders to use wire-exact mappings and removed legacy effort aliasing (e.g., `max-to-xhigh` mapping).
- Updated model registry and provider configurations to support `Max` tier routing, color themes, and UI icon associations.
- Expanded test suites to provide end-to-end coverage for the new reasoning tier, including updated compatibility and fallback scenarios.
- Added `off` and `auto` as valid inputs for the `--thinking` CLI flag.
- Centralized thinking level definitions in `CLI_THINKING_LEVELS` to keep flag options, shell completions, and validation in sync.
- Configured CLI parsing to reject `inherit` as an explicit input to prevent unintended configuration suppression.
- Added `expectSleepNear` to allow ±100ms variance on sleep duration checks.
- Updated `--thinking` test value from `"extended"` to `Effort.XHigh` enum constant.
Wire --hide-thinking launch flag that sets hideThinkingBlock before TUI
init. Display-only: does not disable model reasoning, just hides the
thinking output in the terminal.
- Add hideThinking to Args interface and parseArgs
- Add --hide-thinking flag definition in launch command
- Apply setting via settingsInstance.override in main
