update for redisvl 0.27.2

---

Note

Low Risk
Documentation-only addition of a new versioned content path; no runtime or application code changes.

Overview
Adds a versioned RedisVL 0.27.2 documentation tree under content/develop/ai/redisvl/0.27.2/, published at /develop/ai/redisvl/0.27.2/ with the usual integration landing page, install guide, and section hubs for concepts and user guides.

The bulk of the change is generated API reference pages (schema—including SVS-VAMANA and vector algorithm guidance—cache/LLM extensions, filters, CLI rvl including experimental migrate commands, exceptions, router, rerankers, message history, vector types, and related cross-links). The API index also documents SearchResults alongside the search index classes.
