docs 22 Phase B: gaps 1+2 closed, and the D-on boundary measured on KiCad

Browse source 
Phase B increment recorded in §10. The wx battery is GREEN at D-on (395/1,
the 1 pre-existing) with dispatch contexts, context waits and star transfers
all live - the first clean battery of the migration. Gaps 1 and 2 from the
D-on probe are closed (terminal coroutine finish; wake/refusal semantics),
and a third containment was found and added: an exception escaping a handler
propagates out through drain()'s fiber swap and would otherwise leave the
registry mid-transition, dead-pumping every later wait. Shim carries the new
abandon call; .ci-cache-epoch -> 12.

THE BOUNDARY: on the full KiCad suite D-on loses four canvas-tool specs
(draw-wires, draw-lines, move-with-m, presence-locks move) to `index out of
bounds` in doRewind - the blue screen itself. Real tool coroutines park IN
PLACE inside their bodies, and a star transfer over an already-parked stack
rewinds state the fiber layer cannot see; the harness's coroutines yield
cleanly, so it goes green while KiCad does not (the doc-19 lesson again:
the harness models the shape, not the parks). So D cannot carry KiCad until
the tool-body park sites are contexts too - C+E completion, which §5 already
ordered before the flip. This measurement makes that ordering non-negotiable.

Landing state verified: STAR_DISPATCH=0, kicad 139 passed / 1 (pre-existing
occ-probe glb) = the Phase A baseline exactly, wx battery 395/1.
