docs: re-vendor .ceremony/ from ceremony 0.6.3

#39 moved the two workflow callers to 0.6.3 but left the doctrine mirror at
0.6.1, so BUILDER.md was missing the three clauses that govern signal-then-ready
(ceremony#330, the undraft order, and ceremony#336). Re-vendored all six
manifest files and moved the pin recorded in .ceremony/README.md.
