backend:
- add 429 retry handling with backoff in CivArchive API requests
- add page-scraping fallback for CivArchive model payloads
- normalize CivArchive mirrors with dead/gated/paid/sha256 metadata
- include file metadata and mirror data in normalized archive files
- propagate additional dead/missing status field aliases
- include metadata in normalized CivitAI files
frontend:
- render mirror lists with source grouping, dead-link indicators, and skull icons
- add file badges (primary, type, format, size, fp, mirror count, id)
- improve secondary info in resolve/download methods to include base model
- enhance search panel secondary info with base model and filename
- on selecting a version with empty files, fetch fresh version details
- propagate base model context to CivitAI search state and display labels
Uses an exact alias membership check instead of substring matching to prevent
false positives, e.g. 'zimage' alias no longer incorrectly matches
'zimagebase'.
Raise CivArchiveSearchError in civarchive backend, catch and store it in
source_results in the workflow analyzer, surface it in resolve_download_methods
as an 'error' status, and display error messages in search_panel progress
items and tooltips.
