Compute the gross price to charge so you net a target after fees. FREE.

'Charge X to receive Y' after percentage + fixed processor fees.
Typical input {"net_target": 100, "pct_fee": 2.9, "fixed_fee": 0.30}
returns {"charge": 103.4, "fee": 3.4, "net": 100.0}.

The inverse of processor_fees - solves for gross from a target net. Use
when the payout is the fixed requirement. Not when the price is already
set. Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "net_target > 0 and pct_fee < 100 required"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.
