Operator-requested modal/tagging keyboard improvements: - A2/A3: fandom dialogs autofocus their autocomplete on open; in the character- creation FandomPicker, picking a fandom (keyboard Enter or click) confirms in one step. FandomSetDialog stays autofocus-only (its Save can trigger a merge). - B5: Tab accepts the highlighted autocomplete row (standard convention). - C9: T or / jumps focus to the tag input from anywhere in the modal. - C8: ? toggles a keyboard cheatsheet (corner hint advertises it; Esc closes the cheatsheet first, then the viewer). Builds on the same-batch regression fixes (kebab #711, ESC-after-accept #700, autocomplete scroll-into-view). B6 (keep focus after add) is covered — the input retains focus after adding a tag, and Esc now works after accepting a suggestion. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
