A new setting, referer_blocklist (PIXA_REFERER_BLOCKLIST), lists hosts
whose pages may not show pixa's images. Entries are written and matched
as allowlist_hosts are, with the same matcher. Both image routes check
the Referer before the signature, the cache and the upstream fetch, and
answer 403 with the JSON error, so a blocked request costs nothing and
is refused whether or not the image is cached. No Referer, or one that
does not parse, is served; README.md says this makes the list easy to
get around. An entry of either host list that is not a host name
(letters, digits, hyphens, underscores, dots, at most one leading dot)
or an IP address now aborts startup naming the setting and the entry.

config.example.yml moves unchanged to configs/config.example.yml, the
directory REPO_POLICIES.md names for configuration examples. README.md,
the comments in internal/config/config.go and the startup error for the
placeholder signing key name the new path. scripts/manual-test.sh and
its directory are deleted. The handler tests in internal/handlers cover
every check it made except two: fetching a real image from the internet,
and a URL made on the generator page with a ttl answering 410 once the
ttl has passed (#199).
CONVENTIONS.md, a reformatted copy of the Go HTTP server conventions, is
deleted, as REPO_POLICIES.md links the canonical document.
