- 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.
- Updated the status-line path segment to detect project directories under OS scratch roots and strip the scratch root when rendering.
- Switched scratch-root paths to use the new icon.scratchFolder glyph and registered that symbol across theme variants.
- Added tests covering scratch-root trimming, nested scratch subpaths, and non-scratch fallback icon behavior.
- Added GoalRuntime with wall-clock and token accounting, budget steering, and lifecycle operations (create, pause, resume, drop, complete).
- Exposed goal tool as a hidden agent tool, activated only when goal mode is enabled.
- Integrated goal continuation loop in InteractiveMode with auto-submit between turns.
- Added status line segment and theme icons for goal mode state.
- Added loop-mode command handling in interactive mode, including enable/disable toggling, repeated auto-submission scheduling, and Escape-based cancellation.
- Propagated loop mode state to the status line via a renamed `mode` segment that now renders plan or loop status, and updated presets/theme assets for the new loop icon.
- Migrated persisted status-line segment usage from `plan_mode` to `mode` in configuration defaults and normalization so legacy settings continue to load.
