[srimon12]

Summary

This PR adds richer Qdrant payload index support to QQL and exposes the tenant-optimized indexing path end to end.

Changes

• added advanced CREATE INDEX ... WITH { ... } support for:
  • keyword
  • uuid
  • text
• added tenant/index options for keyword and uuid:
  • is_tenant
  • on_disk
  • enable_hnsw
• added text index options:
  • tokenizer
  • min_token_len
  • max_token_len
  • lowercase
  • ascii_folding
  • phrase_matching
  • stopwords
  • on_disk
  • enable_hnsw
• added uuid as a supported payload index type
• added collection-level HNSW { payload_m: <int> } support
• updated SHOW COLLECTION to return structured payload index details
• updated docs, CLI help, parser tests, and executor tests

Examples

CREATE COLLECTION tenant_docs USING HYBRID HNSW { payload_m: 16 }

CREATE INDEX ON COLLECTION tenant_docs FOR tenant_id TYPE keyword
WITH { is_tenant: true, on_disk: true, enable_hnsw: true }

CREATE INDEX ON COLLECTION tenant_docs FOR doc_id TYPE uuid
WITH { on_disk: true }

CREATE INDEX ON COLLECTION tenant_docs FOR title TYPE text
WITH { tokenizer: 'word', min_token_len: 2, lowercase: true, phrase_matching: true }

Notes

This PR enables Qdrant's tenant-aware indexing path in QQL, but it does not add application-level tenant authorization or automatic tenant filtering. Tenant isolation for access control still belongs in application logic.
