giles b0b0a0592b host: durable lazy sessions — logins survive a restart
Sessions were in-memory, so a restart logged everyone out (same class as the
relation wipe). Move them to the durable store, but LAZILY so anonymous/crawler
traffic doesn't spam it: session/create mints a sid with no row; the row appears
on the first session/set (a login). A per-boot epoch (one durable write at
startup, host/session-init!) keeps sids unique across restarts without a write
per request.

- lib/host/session.sx: lazy backend (create = no row, set = create row,
  exists = row written) + epoch/in-memory-counter sid generation.
- serve.sh: point the session store at the durable backend + host/session-init!.
- blog.sx: host/current-principal is now a durable read, so host/auth-footer
  (home + post footers) had to move OUT of the quasiquote into let bindings —
  a perform during page-tree build raises VmSuspended (the whole site 500'd for
  a beat). Principal computed once per page.
- 2 session tests: create writes no row, set creates the row.

249/249. Verified live: site renders (anon + authed), login + footer survive a
container force-recreate.

# host-on-sx live server launcher. Loads the kernel stdlib, the subsystem
# libraries, and the host modules into one sx_server process, then calls
# (host/serve PORT ...) which binds the native http-listen server to the
# Dream-shaped host app. Runs in the FOREGROUND (http-listen blocks), so this
# doubles as a container entrypoint and a local launcher.
#
# Usage:
# bash lib/host/serve.sh # serve on $HOST_PORT (default 8910)
# HOST_PORT=8920 bash lib/host/serve.sh # pick a port
#
# The module list is kept identical to lib/host/conformance.sh so what serves is
# exactly what the suites verify.
