v1.0

[Rafnuss]

API rename/cleanup for v1.0

• Renames toward clearer names (config2tibble -> config_to_tibble, add_gldp_soi -> read_soi, read_gdl -> read_soi_gld, version() -> gldp_version()).
• New deprecation layer was added to keep compatibility during transition.
• Accessors were consolidated into one file and old per-resource files removed.

Versioning and migration framework

• New versioning/upgrade pipeline added (main -> v0.x -> v1.0), with substantial logic in upgrade steps.
• create_gldp() and schema/version handling were heavily refactored for the v1.0 model.

Zenodo workflow refactor

• Old write-side helpers were removed.
• New read-side flow introduced with dedicated helpers (read_zenodo, fetch/download/metadata split).

Validation and metadata logic refactor

• validate_gldp was significantly reworked.
• update_gldp and merge_gldp logic were simplified/updated.
• print/plot methods were refactored.

Dependencies/CI/test structure

• leaflet moved from Imports to Suggests; magrittr removed from Imports.
• Workflow files were updated.
• Tests were reorganized and expanded (notably upgrade/read_zenodo/validate coverage).
