feat(phase35): implement context in SearchView

Context creation:
- Creates 'search' context when playing track from results
- Uses search query as ID and 'Search: {query}' as label
- Applies to both All tab (first 6) and Tracks tab (full list)
- Stack icon will show "Playing from: Search · {query}"

Search view now fully integrated with context system.
