#44: [spec] Port MailSweep to Synchronous Rust

What to build

Set up the root Cargo project structure and implement the core domain models (EmailHeader, Folder, UID, UIDVALIDITY, Config, MailSweepError), environment loading with dotenvy, and pure RFC codecs (multi-pass RFC 2047 MIME decoding, RFC 3501 Modified UTF-7 folder codec, BODYSTRUCTURE attachment inspection, and RFC 2369 / RFC 8058 List-Unsubscribe extraction) verified against test vectors.

Acceptance criteria

  • Root Cargo.toml configured with standard dependencies (email-encoding, encoding_rs, dotenvy, thiserror, serde, serde_json).
  • Pure RFC 2047 MIME decoder handles multi-pass encoded-words across UTF-8, ISO-8859-*, and Windows-125x charsets.
  • RFC 3501 Modified UTF-7 encoder/decoder handles non-ASCII international folder names without corruption.
  • BODYSTRUCTURE parser accurately detects PDF attachments and embedded media flags.
  • RFC 2369 / RFC 8058 parser extracts valid URL and mailto unsubscribe endpoints from headers.
  • Domain models (EmailHeader, Folder, UID, UIDVALIDITY, Config) and structured MailSweepError enums implemented.
  • cargo test, cargo fmt --check, and cargo clippy --all-targets --all-features -- -D warnings pass with 0 warnings.

  • None (can start immediately)
