- Add proton-bridge as optional dep behind `proton` feature flag
- New proton-bridge/src/lib.rs: pub fn start() spins a background Tokio
thread, pre-binds ports, and signals readiness via mpsc before returning
- src/main.rs: conditionally starts bridge before TUI enters raw mode;
derives effective IMAP/SMTP config via Provider enum
- src/config.rs: add Provider enum, optional imap/smtp, ProtonConfig/
BridgeConfig mirrors, effective_imap/smtp() helpers
- Remove all per-operation eprintln!/println! from imap_server, smtp_server,
and api.rs that fired during TUI operation and corrupted the display
- config.toml.example: unified format covering both imap and proton providers

- Convert tuimail repo to Cargo workspace with tuimail and proton-bridge members
- Add proton-bridge binary crate with config, SRP 6a, and auth modules
- Implement ProtonMail SRP 6a exactly matching go-srp:
- Little-endian bigints throughout
- expandHash = SHA512(data||0..3) producing 256 bytes
- k, u, M1, M2 all via expandHash with 256-byte normalised inputs
- Password hashing v3/v4: bcrypt($2y$, salt+proton) + expandHash(output||N)
- Authenticate against Proton API (auth/info → auth/v4), verify server proof
- Persist session (UID, access/refresh tokens) to session.json
- Add bridge.toml and session.json to .gitignore (contain credentials/tokens)
- Add PROTON.md with full build plan for the mini-bridge
