filter: a reload builds the snapshot one source at a time, and the startup pass reloads only when a source changed or was not enforced

 ### Changed

+- **Blocklists take less memory, and a refresh peaks lower.** A list that names a domain both on its own and with its subdomains, as Adblock-style lists do for every entry, now stores that name once instead of twice. A reload reads one list's compiled files at a time instead of all of them at once, and the startup pass no longer rebuilds the blocklists when no list was due for a refresh.
 - **Each database connection keeps a page cache sized for its job** instead of SQLite's 2 MiB default on all seven: 256 KiB for the configuration database and for retention, 1 MiB for the query-history writer and reader.
 - **The documentation is written for people running nxdns.** It starts from Get started, which downloads a release instead of building from source, and drops the API reference, the troubleshooting page and the performance pages. It is published at <https://nxdns.sh/docs/>, and `INSTALL.md` in the tarball links there.
