Client.call treated a frame carrying our id and neither result nor error
as success, so CallTool returned an empty string and no error: the act
is logged as run and the tool never ran, and ListTools returned an empty
catalogue silently. httpTransport.Call already refused exactly this and
names it 'the one answer that lies'; stdioTransport.Call did not, so the
refusal depended on which door the server was behind. Refused centrally
now, so both transports are covered.
ReadResource collapsed 'not configured' and 'configured but down' into
ErrNoServer by discarding lookup's configured return. Manager.Call keeps
them apart on purpose, since a caller needs the distinction to avoid
proposing a capability that already exists.
internal/memeval was read end to end and is clean. No commit there.
