Bench round 3 (testlogs/riomash-patched-62500-sw): lamp glitches
persisted because reply-resolution was type-blind — an analog reply
still crossing USB from the previous poll could falsely confirm the
NEXT command (usually a lamp write) before the board judged it. Now a
reply resolves only its MATCHING pending request (analog/version/
check); ACK/NAK stay type-blind, which is safe because the board's TX
ISR prioritizes ACK/NAK ahead of reply data, so a command's ACK cannot
trail into its successor's window. Budget-exhausted drops settle 10ms
before releasing the gate so late stragglers land on an empty pending.
New test: a stray AnalogReply must not resolve a pending lamp command.
283 green; selftest regression unchanged.
