* feat(web-shell): add keyboard-nav and IME-safe filter hooks
Two reusable hooks for list-style dialogs:
- useListboxKeyboard: Arrow/Home/End/Enter navigation driven by an active
index, with a "keyboard mode" flag to suppress hover. Yields modified-key
combos (Cmd/Ctrl/Alt/Shift), Home/End in text inputs, and Enter on focused
buttons/links to native handling.
- useFilterInput: IME-composition-safe search state so a filtered list does
not refire on every intermediate pinyin character (commits on compositionend).
* feat(web-shell): DialogShell Escape/backdrop close and focus management
Give every dialog shared, accessible dismissal and focus behaviour:
- Escape closes (guarded during IME composition so it cancels the
composition, not the dialog)
- click on the backdrop closes
- Tab is trapped within the panel, wrapping at both ends
- focus moves into the dialog on open and is restored to the opener on close
* feat(web-shell): overhaul list-dialog interaction and accessibility
Unify interaction across the model, theme, approval, resume, tools, delete,
release and rewind dialogs:
- keyboard navigation via useListboxKeyboard, with a roving highlight that
opens on the current value and does not fight the mouse
- consistent selection visuals: a single roving highlight plus a persistent
"current" accent bar + checkmark; options are role=option divs (no stray
focus ring)
- IME-safe search via useFilterInput; fix Chinese-input jitter in the
resume/delete/release search boxes
- accessibility: role=listbox/option, aria-activedescendant, and aria-selected
bound to the current value rather than the roving highlight
- destructive dialogs keep Enter non-destructive where a confirm button is the
commit (delete/release); rewind confirms on Enter like a single-select picker
Refactors:
- extract shared SessionRow used by resume/delete/release
- rename resume-picker-* CSS primitives to picker-* (they are shared by all
list dialogs, not resume-specific)
Adds regression tests for the model duplicate-current fix, release hover
selection, rewind Enter, the listbox/aria wiring, and the shared hooks.
* fix(web-shell): address dialog interaction review feedback
Follow-up fixes from upstream review:
- DialogShell closes on completed backdrop clicks instead of mousedown, and its
Tab trap now also catches the panel-focused fallback case
- ToolsDialog now has full listbox semantics (ids, aria-activedescendant,
aria-expanded)
- Rewind keeps the roving cursor separate from the confirmed target; Enter only
confirms, and the danger button executes the rewind
- Model/Approval aria-selected now reflects the actual current value; model
highlights stay in bounds when the model list shrinks
- Home/End and modified arrow-key combos yield to native text navigation in
search inputs; Escape yields to IME composition in DialogShell
- Dead picker CSS and duplicate declarations removed; extra regression tests
added for reviewer-raised edge cases
* fix(web-shell): harden shared dialog keyboard and IME handling
* fix(web-shell): tighten dialog shell focus, stacking, and backdrop behavior
* fix(web-shell): align list dialog selection semantics and add coverage
