Subject: [PATCH] feat(web): add GraphSearch view with FTS5 search and type
 filtering
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implements Graph Search interface with full-text search capabilities:

SearchResult.svelte:
- Compact card showing node type badge, status badge, title, description
- Node type-specific colors (goal=purple, task=blue, decision=pink, etc.)
- Truncates description to 150 chars with ellipsis
- Click handler navigates to appropriate view based on node type:
  - goal/task → task-tree view
  - decision/option → decision-graph view
  - observation/outcome/revisit → task-tree view
- Uses button element for a11y compliance

GraphSearch.svelte:
- Search bar with text input and search button (Enter key support)
- Filter bar with toggles for node types: All, Goals, Tasks, Decisions, Options,
  Outcomes, Observations, Revisits
- Results list showing matching nodes with result count
- Empty states for no query, no results, or project not selected
- Requires project selection (prompts user to select first)
- Integrates with search store (query, results, nodeTypeFilter, loading, error)

Updates App.svelte to import and render GraphSearch for graph-search route
