sync: import updated schemas from beckn/schemas

[nirmalnr]

Summary

Syncs all logistics domain schemas from the upstream beckn/schemas repository into this repo. This is part of a consolidation effort to make this repo the canonical home for all logistics-related schemas, after which the beckn/schemas repo will no longer maintain them.

What changed

Synced from upstream (beckn/schemas)

Updated all 35+ logistics domain schema folders (v2.0) with:

• Added schema.json — formal JSON Schema definitions (replaces legacy attributes.jsonschema.yaml)
• Added context.jsonld — JSON-LD context for semantic interoperability
• Added vocab.jsonld — vocabulary/term definitions
• Added versioned README.md per schema
• Updated attributes.yaml — attribute-level documentation and types
• Removed attributes.jsonschema.yaml — deprecated format, superseded by schema.json

Schemas updated include: Alert, CancellationPolicy, Carrier, Consignment, Contact, Courier, DeliverySlot, Driver, Fare, FareBreakup, Hub, Logistics, LogisticsAlert, LogisticsCancellationPolicy, LogisticsDriver, LogisticsFare, LogisticsFareBreakup, LogisticsFeedback, LogisticsOperator, LogisticsPlace, LogisticsRating, LogisticsReceipt, LogisticsRoute, LogisticsSupportCase, LogisticsVehicle, Operator, Package, Proof, Rating (v2.0 + v2.1), ReturnPolicy, Route, Shipment, SupportCase, TrackingUpdate, Vehicle, Waypoint.

Kept as-is (this repo only)

Feedback, Place, and Receipt schemas exist only in this repo and are not present in beckn/schemas — these are preserved unchanged.

Migration note

Once this is merged, the above schemas will be maintained exclusively in this repo. The beckn/schemas repo will eventually remove them.
