Remove the MinIO/S3 storage backend entirely. The filesystem backend is
fully implemented, already used in production, and a migrate-storage tool
exists for any remaining MinIO deployments to migrate beforehand.
Changes:
- Delete MinIO client implementation (internal/storage/storage.go)
- Delete migrate-storage tool (cmd/migrate-storage, scripts/migrate-storage.sh)
- Remove MinIO service, volumes, and env vars from all Docker Compose files
- Simplify StorageConfig: remove Endpoint, AccessKey, SecretKey, Bucket,
UseSSL, Region fields; add SILO_STORAGE_ROOT_DIR env override
- Change all SQL COALESCE defaults from 'minio' to 'filesystem'
- Add migration 020 to update column defaults to 'filesystem'
- Remove minio-go/v7 dependency (go mod tidy)
- Update all config examples, setup scripts, docs, and tests
- frontend-spec.md: rewrite CreateItemPane spec for dynamic form
rendering from form descriptor, replace CategoryPicker three-column
spec with multi-stage domain/subcategory picker, replace useCategories
hook with useFormDescriptor, update form sections to dynamic field
groups, mark hierarchical categories as implemented, remove
sourcing_link/standard_cost from item-level DB columns, update types
and implementation order
- SPECIFICATION.md: rename /api/schemas/{name}/properties endpoint to
/api/schemas/{name}/form
- Mark Phase 4 (remove Go templates) as complete
- Update architecture: SPA serves at / via NotFound handler
- Update overview to past tense (migration is done)
- Update file/line counts (~40 files, ~7,600 lines)
- Mark backend changes 1-3 and 5 as implemented
- Reorganize remaining work section
