Teknium 8fd9fafc84 fix: handle Anthropic Sonnet long-context tier 429 by reducing to 200k (#4747) ...

Anthropic returns HTTP 429 'Extra usage is required for long context
requests' when a Claude Max subscription doesn't include the 1M context
tier. This is NOT a transient rate limit — retrying won't help.

Only applies to Sonnet models (Opus 1M is general access). Detects
this specific error before the generic rate-limit handler and:
1. Reduces context_length from 1M to 200k (the standard tier)
2. Triggers context compression to fit
3. Retries with the reduced context

The reduction is session-scoped (not persisted) so it auto-recovers
if the user later enables extra usage on their subscription.

Fixes: Sonnet 4.6 instant rate limits on Claude Max without extra usage
