Change identifier prefix from 'urn:air' to 'urn:ai'

 We are changing the primary URN namespace identifier (NID) from `ai` to `air` to ensure the NID is at least three characters long. 
 
 The new pattern will be:
-`urn:air:<publisher>:<namespace>:<agent-name>`
+`urn:ai:<publisher>:<namespace>:<agent-name>`
 
 This change also aligns with the latest agreed alignments across with ai-catalog.
 
 ## Consequences
-- All schema references, OpenAPI documents, CDDL specifications, and mock data have been updated to use `urn:air:` instead of `urn:ai:`.
+- All schema references, OpenAPI documents, CDDL specifications, and mock data have been updated to use `urn:ai:` instead of `urn:ai:`.
 - This ensures full compliance with standard URN parsers and avoids short-identifier constraint issues.
 - Implementers must update their identifier schemas to use the `air` NID.

 * **JSON Structural Integrity**: Parses the manifest payload to ensure it is valid, uncorrupted JSON.
 * **JSON Schema Draft 2020-12 Conformance**: If the Python `jsonschema` library is installed (`pip install jsonschema`), the tool automatically runs a strict schema-level validation using the official [ai-catalog.schema.json](../spec/schemas/ai-catalog.schema.json) file.
 * **Strict URN Pattern Matching**: Enforces that each entry's `identifier` adheres strictly to the domain-anchored URN namespace format defined in the spec:
-  `urn:air:<publisher>:<namespace>:<agent-name>` (RFC 8141).
+  `urn:ai:<publisher>:<namespace>:<agent-name>` (RFC 8141).
 * **Value-or-Reference Delivery**: Enforces the mutual exclusivity constraint of the specification. Each entry **MUST** contain precisely one of either `"url"` (remote reference) or `"data"` (embedded payload), and will fail if both or neither are provided.
 * **Ecosystem Attributes Validation**:
   * Checks that `"representativeQueries"` contains between **2 to 5** natural-language queries to ensure high-performance semantic vector embeddings.
