Context

The SERP API cache TTL is hardcoded to 24 hours in the codebase. Operators cannot tune caching behavior without modifying source code.

Roadmap reference: ROADMAP.md > P2 > Backend > SERP cache TTL is hardcoded

What to do

  1. Add SERP_CACHE_TTL_HOURS to config.py (default 24).
  2. Replace the hardcoded value in the cache logic with the config value.
  3. Add the variable to .env.example with a comment explaining its effect.

Acceptance criteria

  • Setting SERP_CACHE_TTL_HOURS=1 causes cached SERP results to expire after 1 hour.
  • The default behavior (24 hours) is unchanged when the variable is unset.
  • The variable appears in .env.example.

Triage: Priority Tier 4 - P2 Infrastructure and Config

This is a P2 infrastructure/config improvement. Should be worked after Tier 1-3 items.

Agent type: @developer (small, well-scoped change)

Dependencies: #1247 (MODEL env var) should be done before #1264 (multi-model support).
