tuimail/proton-bridge/Cargo.toml
Shautvast 05b6aac692 Add proton-bridge crate: workspace setup and SRP authentication (Step 2)
- 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
