v0.8 deprecate AnonCreds DataIntegrity namespace

[rmlearney-digicatapult]

packages/core/src/modules/vc/anoncreds-w3c-credential/deprecated.ts

This is a file containing temporary compatibility aliases for the AnonCreds W3C credential rename.

Major-version cleanup checklist (separate from DataIntegrity namespace):

1. Delete packages/core/src/modules/vc/anoncreds-w3c-credential/deprecated.ts
2. Stop exporting deprecated.ts from the credential barrel packages/core/src/modules/vc/anoncreds-w3c-credential/index.ts
3. Remove @deprecated getters:

• packages/core/src/modules/vc/linked-data-proofs/models/W3cJsonLdVerifiableCredential.ts (dataIntegrityCryptosuites)
• packages/core/src/modules/vc/linked-data-proofs/models/W3cJsonLdVerifiablePresentation.ts (dataIntegrityCryptosuites)

4. Remove class/path compatibility alias packages/anoncreds/src/anoncreds-rs/AnonCredsDataIntegrityService.ts

Notes:

• DataIntegrityProof (string proof type) is protocol-level and must remain.
• This checklist targets compatibility aliases only.
• Internal consumers should use canonical W3C credential symbols only.
