bd: update sync.remote

Pin Na1w/marmel to commit fd551ae. Upstream publishes no tags or
releases, so the version uses the shape nix-update generates for a
tagless repository, keeping `nix-update --version=branch=main` usable.

The test suite runs green (325 lib tests plus all integration suites)
with two accommodations, both documented in the derivation:

- Export SSL_CERT_FILE from nixpkgs cacert. rustls refuses to construct
  a reqwest::Client without a system trust store, which failed 38 tests
  with "No CA certificates were loaded from the system".
- Serialise the test harness. The lib suite shares process-global worker
  registries and steer/abort buses, so manager-loop tests fail
  nondeterministically on parallel threads: one unchanged derivation
  produced 3 failures, then 1 failure, then 0 with --test-threads=1.
  No test is skipped or filtered.

Annotated example configs are installed to share/doc/marmel/examples/.
Role prompts are embedded via include_str!, so there is no runtime data
directory. Upstream README states MIT but ships no LICENSE file and no
Cargo.toml license field.
