Subject: [PATCH] core: embed the BIP-39 wordlist as the upstream file

The list was transcoded into Haskell, which can only be audited by reading
2048 words against the source. The upstream english.txt is vendored instead
and embedded at compile time, so auditing it is one sha256sum, and a test
pins that checksum so the copy cannot drift.

file-embed moves into the library, where it was already a dependency of the
executables and the test suite.
