## Title

    Proposed fix: [langchain-aws] count_tokens ignores tools — 'Tool schemas are not yet supported by AWS Bedrock count_tokens API. Ignoring tools parameter.' (undercounts tool-heavy prompts)

## Body

    Recommended action: Add a safety margin for tool schema tokens (or count with a provider that includes tools) and treat CountTokens as an estimate.
    
    Option: Budget extra tokens for tools [evidence: documented_workaround]
    Steps:
    1. Estimate tool schema tokens separately and add them.
    Expected: Fewer surprise overflows.
