Lift the sign-off DRAFT note, fix footer/cursor CLAUDE.md overclaim, honest-en the readout-width test, trim duplicated rationale

Removed DRAFT marker on approved readout strings; corrected "paint and cursor cannot disagree" to note drag-cue suppression; renamed the width test to state it only bounds character count, not pixels; trimmed restated rationale to its CLAUDE.md/header home.
