Implements complete Time-To-Live operations with proper error handling and optimization. Adds 3 scalar functions matching Redis protocol. ## Features - redis_expire(key, seconds, secret) → Set TTL in seconds - redis_ttl(key, secret) → Get remaining TTL (-2/-1/positive) - redis_expireat(key, timestamp, secret) → Set expiry at Unix timestamp ## Implementation - 4 protocol formatters (formatExpire, formatExpireAt, formatTtl, parseIntegerResponse) - Error handling with try-catch blocks - Secret access optimization (extract once before loops) - Follows AGENTS.md patterns ## Files changed - src/redis_extension.cpp: +135/-2 lines - docs/README.md: +20 lines - test/sql/redis.test: +15 lines - .gitignore: +5 lines

Adds three scalar functions for managing key time-to-live in Redis:
Implementation details:
All functions follow existing patterns and pass unit tests. Live-tested against local Redis instance - all TTL operations working correctly.
