Walkthrough

This PR introduces site-scoped search functionality to the command palette, enabling users to search within specific websites directly from the search interface. It adds a new SiteSearchEntry data model with preset configurations for popular sites, integrates site search UI and keyboard handling into the command palette, provides settings components for managing site search entries, and persists settings via the NookSettingsService.

Changes

Cohort / File(s)	Summary
Site Search Data Model CommandPalette/SiteSearch.swift	New SiteSearchEntry struct with Codable/Identifiable/Equatable conformance; includes URL generation via searchURL(for:), prefix matching via matches(prefix:), and static defaultSites property with nine popular sites (YouTube, GitHub, Reddit, X, Wikipedia, Amazon, Twitch, Spotify, Stack Overflow).
Command Palette Integration CommandPalette/CommandPaletteView.swift	Added activeSiteSearch state property; computed properties siteSearchMatch and visibleSuggestions to filter suggestions when site search is active; enhanced keyboard handling for Tab (activate site search), Escape/Delete/Backspace (exit site search); updated icon and placeholder to reflect active site search; modified handleReturn to resolve queries and navigate via site-specific URLs; adjusted suggestion rendering and selection logic.
Settings UI Components Nook/Components/Settings/SettingsView.swift	Added SiteSearchSettingsCard component for listing, editing, and deleting site search entries with Reset to Defaults action; added SiteSearchEntryEditor for creating/editing entries with name, domain, URL template, and color fields; expanded formatTimeout function implementation.
General Settings Nook/Components/Settings/Tabs/General.swift	Integrated Site Search section with list of existing entries, add/delete actions, and reset button; wired sheet presentation for SiteSearchEntryEditor to append new entries to nookSettings.siteSearchEntries.
Settings Persistence Settings/NookSettingsService.swift	Added siteSearchEntries property with JSON encoding/decoding for user defaults; initializes from persisted data or falls back to SiteSearchEntry.defaultSites.

Poem

🐰 Hop, skip, and search through sites so keen,
Site-scoped queries paint the screen,
With YouTube, GitHub, Reddit's glow,
The command palette steals the show!
Tab to leap, Escape to flee,
A search experience wild and free! 🔍✨
