Subject: [PATCH] fix: update TOTAL_CONTEXT_TOKENS to 1M for Kiro context
 window upgrade

Kiro has upgraded its context window from 173k to 1M tokens. The hardcoded
TOTAL_CONTEXT_TOKENS: 172500 causes input_tokens in the converted Claude
SSE response to be severely underestimated (~17% of actual value).

input_tokens is calculated as:
  totalTokens = TOTAL_CONTEXT_TOKENS * contextUsagePercentage / 100
  inputTokens = totalTokens - outputTokens

With the old 172500 constant, a request with real input of 169,944 tokens
gets reported as ~35,000 tokens, causing downstream billing systems to
undercharge by ~5x.
