teknium1 a54405e339 fix: proactive compression after large tool results + Anthropic error detection ...

Two fixes for context overflow handling:

1. Proactive compression after tool execution: The compression check now
   estimates the next prompt size using real token counts from the last API
   response (prompt_tokens + completion_tokens) plus a conservative estimate
   of newly appended tool results (chars // 3 for JSON-heavy content).
   Previously, should_compress() only checked last_prompt_tokens which
   didn't account for tool results — so a 130k prompt + 100k chars of tool
   output would pass the 140k threshold check but fail the 200k API limit.

2. Safety net: Added 'prompt is too long' to context-length error detection
   phrases. Anthropic returns 'prompt is too long: N tokens > M maximum'
   on HTTP 400, which wasn't matched by existing phrases. This ensures
   compression fires even if the proactive check underestimates.

Fixes #813
