feat: add global cross-project session search to projects view

Add a search bar to the ProjectList that filters projects by name (instant, client-side) and searches across all projects' sessions (debounced backend call). Results are grouped by project with expandable accordion snippets, highlighting, and action buttons. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
