feat(v4.0.0): the wait replaces looking and the console release; step 6d written up

Browse Source 
The engine's console release (v4_fabric_interrupt_error), a device's
pending, and the count of words since a look are removed: nothing uses
them.  MESH.md 4.1, 7b and 7c say what was built, where it differs from
what was approved and why, and what is still a limit; step 6d is marked
built, with the defects found on the way.

make -C v4 test and sanitize at both widths, hosted-check, lint; three
bare-metal boots.  POST 538 of 538, word_count=317,
dict_hash=0x6a39c0bb9d183418 on all six.
