d54976e756 Report update errors or timeouts.
Looking through Sentry history, `update <domain> err:` is an extremely
high SNR signal of something going wrong; from configuration errors on
our side, to people pushing too-large git repositories and it failing.
Either way we should know.

188c66c434 Use an ad-hoc type to deserialize JSON webhook payload.
This is both better structured, and avoids crashes on invalid payloads
that would occur before this commit due to a lack of checking for nil
in the maps.

5b8cb4ba11 Clean up Caddyfile, removing Fly.io-isms.
The grebedoc.dev infrastructure is no longer directly tied to
the container built from this repository, so we don't have to
pollute the configuration with Fly.io-isms.

a85905bd31 Fix time-based cache expiration practically never working.
config.MaxAge is now a nanosecond value, and multiplying it by
time.Second (number of nanoseconds in a second) will make it too large
for the cache expiry algorithm to have any effect.

a14f9e1e6c Use int64, not uint32, for sizes in the manifest.
This change eliminates a number of rather sketchy casts.

This conversion is a no-op for the wire format, explicitly per
Protobuf documentation.

b1ef57d32a Only cache NotFound errors from S3 backend, rather than any errors.
We need to cache NotFound responses to avoid hitting the backend
whenever there's a flurry of requests for the same invalid domain.
But caching any kind of error, including context cancellation, results
in poisoning the cache with that error, e.g. if the domain exists but
the client that requested it first did not wait for the response.

217f3a9320 Switch log handling to slog.
This currently doesn't add any structure to the logs, changing just
the handler and output format. It does also add Sentry logging support.

The `log-format` configuration value now accepts values `none`, `text`,
and `json`.
