purge: remove Anthropic references from timmy-home

Enforces BANNED_PROVIDERS.yml — Anthropic permanently banned since 2026-04-09.

Changes:
- gemini-fallback-setup.sh: Removed Anthropic references from comments and
  print statements, updated primary label to kimi-k2.5
- config.yaml: Updated commented-out model reference from anthropic → gemini

Both changes are low-risk — no active routing affected.
