Say which version this is: 0.8.0

A hundred commits since 0.7.0, and the face subsystem in them is not a set of
fixes — it is the difference between a feature that was shipped and one that
works.

Clustering finished at all for the first time: the old agglomeration rescanned
every live pair and recomputed average link from scratch after every merge, and
on a real library it did not return. A sparse above-threshold graph, connected
components and Lance-Williams sums put 1,813 faces at 0.28s, and the merge
threshold moved to 0.80 because the old 0.90 was measured — not guessed — to
leave a third of the library ungrouped.

Faces are no longer indexed at any size or any sharpness. Both floors were
measured over the real library with `face_index --quality`: 32 source pixels
across the aligned crop, and a contrast-invariant sharpness that catches the
large-but-blurred face whose confident, wrong embedding used to weld two people
together.

The crop is cut once and kept, so the People screen is no longer a derivative of
a thumbnail cache entitled to evict anything at any moment. The screen itself
became usable: the faces wrap into a grid instead of running off the edge, the
header fits a phone, a group can be set aside, and a person's photographs are a
button away — as a union or an intersection of several people.

And face sync now reaches the other device. Re-indexed images re-export, shards
written before the crop and index-time columns are repaired rather than failing
every insert, people and the user's judgements about them cross the wire at all,
and the pass says what it is doing while it does it.

The Android versionCode follows without being restated — package.sh packs
MAJOR*10000 + MINOR*100 + PATCH, so 0.8.0 is 800, above the 700 already on
devices and therefore an upgrade rather than a refusal. `pkgrel` returns to 1,
since this is a new version rather than a rebuild of the last one.
