Release v0.6.0

Release v0.6.0

Adds the imports module: bringing catalogue records into a workspace from a CSV, with a full stewardship trail so every import is reversible.

Imports module

• A per-tenant imports capability (off by default), enabled or disabled per tenant by operators.
• CSV upload with named validation and header-matched mapping profiles — per-workspace, uniquely named, versioned, and shareable read-only across a federation — carrying a library of transforms (copy, default, constant, labelled concatenate, split, controlled-vocabulary remap, carry-forward) and an English/Spanish archival date parser with a certainty vocabulary.
• Starter profiles for common export formats (AtoM ISAD(G), AGN FUID, EAP, MEAP) and a generated "Fisqua template" for archives starting a catalogue from nothing.
• A four-step journey — Upload, Check, Dry run, Import. The readiness Check groups problems by class and turns each required-field gap into an explicit, recorded decision before a dry run is allowed; identifier problems are never an accept option.
• A dry-run report (counts by named reason plus a verbatim rejects CSV), then a reversible commit that runs as a durable workflow, re-derives every row from the staged file, and journals each write with full before-images.
• Revert runs that walk an import's journal in reverse (itself reversible), and runs/run-detail surfaces scoped per workspace.

Stewardship records (groundwork)

• A stewardship_runs envelope (required operator message, justification, kind, revert linkage) with the existing changelog as the journal of record, protected by database-level append-only triggers, and a build-failing journal-coverage test.

Repository form assists

• A country picker (bundled ISO 3166-1, English and Spanish) that fills the ISO country code, a house-convention repository-code suggestion, per-field help text, and operation-level repository gating.
