When archive_folder is set in the project config, artifacts are moved to
numbered archive copies (e.g. x.01.jpg, x.02.jpg) instead of being
overwritten or deleted.
- Build command archives existing artifacts before rebuilding dirty targets
- Clean command moves files to archive instead of deleting them
- Subfolder structure is preserved in the archive directory
- State file is always deleted, never archived
- State filename now derives from config: cards.bulkgen.yaml produces
.cards.bulkgen-state.yaml instead of .bulkgen.state.yaml
- Store resolved prompt text and extra params directly in state file
instead of hashing them, making state files human-readable
- Only file input contents remain hashed (SHA-256)
- Thread project_name through builder and CLI
- Remove hash_string() and _extra_hash() helpers
- Update .gitignore pattern to .*.bulkgen-state.yaml
- Add click as explicit dependency (already bundled with typer)
- Replace typer.echo calls with click.echo + click.style for colorized output
- Add BuildEvent enum and ProgressCallback to builder for decoupled progress reporting
- Remove direct typer dependency from builder module
- Show per-target status with colored labels (skip/ok/fail/...)
- Display elapsed build time in summary
- Colorize graph and clean command output
- Update CLI tests to match new output format
