  1. feat(sql): add x402 and MPP payment lanes (DX-6602) 

    SQL Explorer can run without an account: clusters and schema stay
public, and query pays with x402 drawdown or an MPP session.
qn micropayments (alias pay) shares the existing x402 and mpp runners.

  2. fix(sql): persist a banked MPP voucher when the query fails 

    The MPP query path returned on error before saving the channel, so a
query that failed after the gateway banked the voucher left the cached
cumulative behind the gateway's accepted value. The next query re-signed
that stale cumulative and was refused, stranding the channel. The SDK
now advances the channel whenever the voucher reached the gateway, and
this saves it on both paths before mapping the error.

Also gates the credit and channel error matchers on a 402: the body
markers were alternatives to the status check, so a 500 whose message
happened to contain "insufficient" reported as an empty balance.

Docs: SQL has no per-request --x402 flag, so context.md no longer claims
it is rejected; the no-payer query is documented as exit 1, since a key
is one of three ways to pay; drops an absence-of-feature line from the
README MPP intro.

Tests: a failed query persists the receipt cumulative, sql clusters maps
a catalog error to exit 2, buy-credits clears the gate with --yes, and a
clusters table snapshot.
