terminal-fill: launchpad curves and ETH-quoted v4 pools priced on BasedBot's router family (Robinhood draws 8/40 -> 33/35)

[Flotapponnier]

Why BasedBot's (and Axiom's, GMGN's) Robinhood Chain rows stayed under the ranking floor: 74 to 79 % of the drawn router swaps were unpriced. A probe over the last 40 router swaps (harness nativeRow, keyed node) tallied: no_pool 15, no_quote_leg 7, priced 8.

• no_pool = launchpad bonding curves: one contract per token (same 10,230-byte bytecode), no Uniswap event, its own buy 0xec36bf57… [gas coin in, tokens out, fee 1, fee 2] and sell 0x8113d738… [tokens in, gas coin out, fee 1, fee 2], fees 1 % + 2 % on the gross amount. New rhcurve.go: pool = the reserve's side of the trade, other = the curve's fees, reference = the previous trade on the curve at the reserve-side price (walked in 9,000-block chunks up to two hours: the keyed node caps eth_getLogs at 10,000 blocks and Robinhood Chain makes ~590 a minute). The quote is the gas coin unless an ERC20 moved the amount to or from the curve (stable, WETH, or a token the route bought on the way, priced through that swap: a curve quoted in 0x4a0e65a3… bought on a v3 pool from WETH was 16x off before that). A token launch's first buy (minted to the curve in the same transaction) is rejected as launch_first_trade, not counted as unpriced.
• no_quote_leg = sells against ETH-quoted v4 pools: the PoolManager holds ETH itself, so no ERC20 transfer logs the quote leg. nativeV4Quote: when no ERC20 flow of half the quote or more moved through the manager, the quote is the gas coin at the exchange's price.

Probe after: priced 33, launch_first_trade 5, unpriced 2 (a v4 pool with no previous swap, one quote leg). Spec reference bullet, unpriced-draws bullet and README updated. The same code covers BNB, Base and Ethereum where the router family runs.

Deploy: harness image, worker rebuild + materialize reset (spec).
