- Updated `codexResets.autoRedeem` from a boolean to `unset`/`yes`/`no` in schema and settings types, with updated description text.
- Adjusted Codex auto-reset evaluation to skip checks in `no` mode and to prompt once in `unset` mode before spending, while preserving immediate spend for `yes`.
- Migrated legacy boolean config values to tri-state during settings load and added tests for mode defaults, helper behavior, and migration results.
