fix: verify the metadata database certificate with sslmode=verify-full
- Switch every `metadata_db_sslmode` passed to bincraft in `.crow/` and `local/` from `require` to `verify-full`.
- Pass `sslrootcert = bincraft::postgres_sslrootcert("verify-full")` alongside `verify-full` in the scripts that call `DBI::dbConnect()` themselves, since libpq does not read the system trust store.
- Note in the README that the endpoint serves a Let's Encrypt certificate and how to verify it.

### Classify every compiled package in a slot's flat index, into the ABI cache.
#
# Usage: Rscript local/backfill-abi-classification.R <arch> <codename> [limit]
#
# The per-minor scheme only ever classified packages that passed through the
# build pipeline after it existed. Everything built before that, and not updated
# on CRAN since, has no verdict at all -- and bincraft's risky set is what
# decides whether a flat binary may be carried into a per-minor index. With no
# verdict the answer defaults to "carry it", which is how a base64enc built
# under R 4.4.3 reached R 4.6 clients and died at dyn.load() on SETLENGTH.
#
# The verdict is a property of the source, so it is independent of OS, arch and
# R minor: one slot's backfill populates the cache for every slot. The slot
# argument only selects which flat index to enumerate.
#
# Only packages with NeedsCompilation=yes are classified. A package with no
# compiled code has no symbols to bind and cannot fail this way, so downloading
# its source to prove that would be wasted work.
#
# Resumable: `classify_r_minor_sensitive()` returns cached verdicts without
# touching the network, so a re-run costs one query per package and only the
# unclassified remainder is downloaded.
