Download root rules now accept match_type "tag": the rule hits when any
of its free-text tags equals one of the model's CivitAI tags (trimmed,
case-insensitive), so e.g. all "character" models can be routed to a NAS
root regardless of base model. Rules stay ordered — first match wins
across mixed base_model/tag rules.
- settings normalize keeps tag entries as free text (case-insensitive
dedupe, no base-model whitelist); resolve_download_root gained a tags
parameter and a match_download_root_rule helper
- the download flow passes the version's model tags into rule resolution
- the routing endpoint accepts tags and reports the matched rule; the
versions endpoint ships model-level tags with each version so the
location step can preview tag matches
- the settings rule editor gained a per-rule match-type dropdown; tag
rules edit a comma-separated list (committed on blur/Enter) instead of
the base model checkbox panel
- the download confirmation modal shows "Routed by rule: ..." next to
the preselected root
