Fix the antispam test: pin the rules it scores against, stop live Pyzor
It failed everywhere but upstream's machines, for two reasons:

- The spam rules, which carry every score, came from a path on an
  upstream developer's own disk. Without SPAM_RULES_URL none loaded, every
  score was 0.00 and the combined case came out ham instead of spam at
  13.70. The published rules of spam-filter v3.0.2 are now pinned beside
  the test cases (Apache-2.0 or MIT, taken as MIT; in THIRD-PARTY.md).
  SPAM_RULES_URL still overrides.
- The first combined case expects a Pyzor hit, and its digest (that of an
  empty body) wasn't among the three the test mode answers, so it went to
  a public Pyzor server: it failed offline and would drift with that
  server's counts. Test mode now answers every digest from a fixed table,
  with the empty body's added, and never reaches the network.

The test passes online and offline, alone and with the rest of the SMTP
tests. queue_retry, unrelated, still fails when it runs after the others
in one process, though it passes alone every time.

# Third-party code
INBUXA is a fork of Stalwart. Stalwart is original work by Stalwart Labs LLC,
not a fork of anything, but a few of its files carry code, adapted or ported,
from other projects under permissive licenses. Those parts stay under their own
licenses, not the AGPL, and their notices are reproduced here as the licenses
require. Where a project offers MIT or Apache-2.0, INBUXA takes it under MIT.
`tools/fork/strip.py` lists every such file on each upstream import and names
any this page doesn't cover yet (docs/spec/SPEC.md §2.2). The fork's own code,
and Rust crates pulled in as dependencies, aren't listed here: dependencies
carry their own license files.

## Credited algorithms
These files implement published algorithms and credit their source. No code
is copied, so there's no notice to carry. They're listed so the strip report
doesn't flag them as new.
