DS-076: Build a shared SearchField component

[IbrahimIjai]

Context

Market selectors, pool tables, command surfaces, and future transaction history
all need search input. Rebuilding clear buttons, keyboard behavior, loading
feedback, and result counts in each feature leads to inconsistent interactions.

Scope

• Add a SearchField composed from the shared Input, IconButton, and Spinner.
• Support controlled value, clear action, loading state, and optional result count.
• Provide compact and default sizes.
• Define accessible behavior for search submission and live result updates.

Acceptance criteria

• The control uses the native search input type and has an accessible label.
• Escape clears a non-empty query without unexpectedly closing a parent overlay.
• Clear and loading controls do not change the input width.
• Result-count announcements are debounced and do not fire on every keystroke.
• Tests cover typing, clearing, Escape, loading, disabled, and announcement behavior.

Out of scope

• Implementing filtering, debouncing network requests, or fetching results.
• Replacing the Combobox input for selection workflows.

Hi Maintainer, I investigated the reported behavior and have a solid understanding of the expected result. I'll ensure the implementation is both efficient and maintainable.

Hi, I'd like to work on this issue. I have experience building composable, accessible shared UI components — especially input controls with careful keyboard and announcement behavior.

My plan: build SearchField from the existing shared Input, IconButton, and Spinner, supporting controlled value, clear action, loading state, and an optional result count, in both compact and default sizes. I'll use the native search input type with an accessible label, make Escape clear a non-empty query without closing a parent overlay, keep clear/loading controls from shifting input width, and debounce result-count announcements so they don't fire on every keystroke. Tests will cover typing, clearing, Escape, loading, disabled, and announcement behavior.

Happy to get started right away.
