v1.2.0

Latent Model Organizer 1.2.0

Forge user metadata support:
- Trigger words and Civitai descriptions are written into the <basename>.json
  file that A1111, Forge, and Forge Neo actually read, so they appear in each
  LoRA's Activation text and Description fields.
- New offline backfill (POST /api/backfill-metadata and a Fetcher action) to
  retrofit an existing library from sidecars already on disk, with no hashing
  and no network calls.
- Existing metadata is merged, never replaced.

Fixes:
- Preview files keep the extension the URL serves, so Civitai's animated .mp4
  previews are no longer saved as undecodable .png.

Tooling:
- Shared IntelliJ run configurations under .run/.
