Add OpenCode support, pane-scoped mouse selection, and search

- Provider abstraction (Provider interface) with Claude Code and OpenCode backends
- OpenCode provider reads sessions from SQLite (~/.local/share/opencode/opencode.db)
- Tabbed provider UI with 1/2/tab switching when both providers are available
- Mouse mode always on: click to focus panes, drag-select in content pane with
  auto-clipboard copy, scroll wheel support
- Content search (/) with live debounced highlighting and n/N match navigation
- Session search overlay (/) with global/project scope toggle, debounced results
