fix: stop deducting simulated cache tokens from input_tokens

Kiro backend does not support Anthropic prompt cache protocol.
The local cache tracker simulates cache hits/creation for Claude Code
compatibility, but subtracting those values from input_tokens caused
the reported input_tokens to drop to single digits.

input_tokens now reflects the real value; cache_creation_input_tokens
and cache_read_input_tokens are still reported for protocol compliance.
