Overview
Updates RedisVL documentation for 0.27.1, focusing on filter API behavior, MCP filter safety, and example query strings.

Filter API (filter.md) adds notes that Text ==/!= render values as quoted phrases (with "/\ normalized) while % passes raw patterns (with injection caveats). Num.between and GeoRadius docs now spell out accepted types, bounds, inclusive options, and TypeError/ValueError cases; Geo documents Redis’s ±85.05° latitude indexing limit.

MCP (mcp.md) revises how caller filters stay inside their clause: text eq/ne is handled inside Text (quoted phrase); text like stays raw with delimiter escaping at the MCP boundary.

Complex filtering guide wraps single-clause filters in parentheses in sample Redis query strings (e.g. (@credit_score:{high}), (@job:("engineer"))) and adds the same literal vs pattern guidance for Text.
