feat: update search dialog with filter pills and default view (#25753)

Update the ChatSearchDialog with four interaction states: 1. **Default (empty)**: quick actions (New chat, Settings, Personal Skills, View usage) + recent chats list 2. **Focused**: filter-by dropdown overlay with clickable chips (Unread, Archived, PR status, Diff URL) 3. **Active search**: filter pills and/or freeform text with debounced live results showing "N results" count 4. **Parameterized filter**: incomplete pill (dashed border) for filters needing a value (e.g. `pr_status:`); Space or Enter commits the value into a solid pill Filter pills and freeform text are combinable. Backspace on empty text removes the last pill. The filter dropdown overlays content below and dismisses on blur or Escape. Changes: - `ChatSearchDialog.tsx`: manages structured filter state with separate `incompleteFilterKey` tracking, renders filter dropdown, passes recent chats and quick action callbacks - `ChatSearchInput.tsx`: renders completed filter pills (solid border, x dismiss) and incomplete pills (dashed border) inline with the text input - `ChatSearchResults.tsx`: default view shows quick actions + recent chats instead of the old help text; "No matching chats" is centered in the modal - `ChatsSidebar.tsx`: passes `recentChats`, `onNewChat`, `onOpenSettings` to the dialog <details> <summary>Implementation notes</summary> - No backend changes; reuses existing `chatSearch()` API and `normalizeChatSearchInput()` normalizer - Filter state uses a clean model: `filters` array for committed filters + `incompleteFilterKey` string for the parameterized filter being typed; `freeText` serves dual purpose (filter value when incomplete key is set, otherwise freeform search) - The filter dropdown is absolutely positioned (`top-full`) below the search input, dismisses via container `onBlur` with `contains(relatedTarget)` check - Quick action links (Personal Skills, View usage) use `Link` components that close the dialog on click > Generated with [Coder Agents](https://coder.com/agents) </details>
