Add /items: one merged grid of every item the pub knows about

Browse Source 
cust.ooo linked to one viewer page per kiosk, so every new kiosk meant
another hand-added link. /items selects on "whatever this pub follows"
instead: follow a new kiosk from the pub and its items appear on the next
cache miss, with no code change and no edit to the site.

serveUserFeed already reduced a feed's contact messages into a follow set;
that moves to lib/follows.js so both routes share one implementation rather
than drifting. It also picks up a fix on the way: the old filter passed
messages with no .value through and then dereferenced .value.content on them.

Two properties of the data drive items.js, both verified against the live log
and both quietly wrong to assume otherwise:

  * custodisco is the STRING "true", not a boolean.
  * no custo message has ever set content.channel, so the channel index finds
    nothing and the filter has to read content fields directly. This is why
    /channel/custodisco renders an empty page.

Log order is arrival order, which diverges from publish order whenever an old
feed is backfilled, so the collected set is sorted by timestamp. That makes
"newest first" and the ?before cursor agree; verified as zero overlap between
consecutive pages.

Cards rather than articles: 300 photos in a single column reads like a mailing
list, not an archive. A transfer borrows the photo of the item it transfers and
links to that item's thread, so the grid stays regular and the give is still
legible as a hand-off. Images are lazy, and 267 blobs are held against 301
mints, so a missing photo degrades to a placeholder instead of a broken icon.

serveHome now shows the grid instead of a bare id-lookup box, which was a dead
end for anyone arriving without an id already in hand. The ?id= redirect stays.

The footer commit now comes from .deployed-commit, written by the deploy
script. Deploys are rsync, so the server's checkout keeps whatever HEAD it was
cloned at and `git rev-parse` there names a commit unrelated to the files
actually running.
