v0.2.0

Features

• Similar photo suggestions: new "Find similar photos" button runs a two-stage pipeline. Immich smart search pre-filters by pet description, then the classifier ranks candidates by pet class probability. Replaces the manual search bar.
• Pet description field: each pet now has a short description (2-4 keywords, e.g. "orange tabby cat") used as the CLIP text query for suggestions.
• Shift+click range selection: hold Shift and click a second photo to select the full range in the grid.
• Tagged photos panel: view photos already tagged for the active pet; remove a tag or mark as "not my pets" in bulk.
• Scan status panel: shows last scan time, badge (running/idle/error/never), and per-pet stats (tagged, skipped, errors) after each poll cycle.

UI

• Refs and "Not my pets" grids: 3-column layout, equal height, independently scrollable.
• "Not my pets" panel (formerly Negatives): unified card style with refs, clickable thumbnails linking to Immich.
• "Find similar photos" button moved to the top of the right panel as the primary action.
• Scan and last scan controls moved to the bottom of the sidebar.
• Removed the manual search bar.

Internal

• Negative samples subsampled to 3x pet refs in the classifier to keep class balance without discouraging large negative sets.
• Static files split into style.css and app.js (was a single index.html).
• Backend refactored: data.py for file I/O, immich.py for HTTP helpers (replaces immich_apis.py).
