Plugins were reaching into internal core paths (shopdb.core.models.*, shopdb.extensions, shopdb.utils.*), coupling them to core's file layout and violating the ADR-001 contract. Consolidate onto one versioned surface. - shopdb.api: expand from 2 helpers to the full plugin import surface - db, cache; BaseModel, AuditMixin; core models (Asset, AssetType, AssetStatus, Vendor, Model, Communication, CommunicationType, Location, Setting, AuditLog, Application, AppVersion, OperatingSystem); response + pagination helpers; employee_connection. Documented in PLUGIN-HOOKS.md. - Migrate all 22 plugin source files to import only from shopdb.api (plus shopdb.plugins.base for the ABC). - Drop the printers plugin's legacy MachineType dependency: remove _ensure_legacy_machine_types and the seed_supplies machinetypeid lookup (Model.machinetypeid is nullable; printers carry type via PrinterType). - Guard test test_plugins_only_import_contract_surface scans plugin source and fails on any core import outside shopdb.api / shopdb.plugins.base. - Scaffold templates updated so generated plugins are contract-pure. - Bump __contract_version__ 0.2.0 -> 0.3.0 (additive surface expansion; manifests pin <1.0.0 so they still satisfy). 145 tests pass, naming/style green, app factory boots all 6 plugins.

"""Model-to-supply mapping - data-driven toner/drum/waste part numbers.

Replaces the old hardcoded part-number table. Each row maps one printer
|
|
model to one supply part (a toner of a given color and capacity tier, or a
|
|
drum/waste/maintenance item). Lets new models and their toners be added
|
|
through the API/UI without a code change.
