Record the approach-2 decision and the furniture toggle

Approach 2 chosen, built in the phase order already proposed -- it is a
superset of approach 1, so the ad-detection work still lands first and the
library last.

Advertising is always skipped; the show own intro, cue and credits obey a
single preference defaulting to on, because that is what happens today.

The toggle settles a bootstrapping question the design had left open. A
furniture clip cannot be promoted until a second fetch occasion has
passed, so until then there is nothing to label with. The zero-gap
classification fills that gap: served length equal to declared means
nothing was inserted, so every break is furniture and position decides
which kind; otherwise a break is advertising unless a promoted clip says
otherwise. Day one is correct on the 138 zero-gap episodes and identical
to current behaviour everywhere else.
