feat: M4 Session Manager + demo
ShadeSessionManager wraps X3DH + Double Ratchet into a simple API:
- initialize(), createPreKeyBundle(), encrypt(), decrypt()
- Automatic PreKeyMessage for first message, RatchetMessage after
- Signed prekey rotation, multi-peer sessions, one-time prekey mgmt
- Interactive demo.ts showing full frontend↔backend E2EE flow
80 tests, 0 failures across M1-M4.

feat: Shade E2EE library — M1-M3 complete
Signal Protocol implementation with full X3DH + Double Ratchet:
- M1: Core types, CryptoProvider interface, KDF chain functions,
SubtleCrypto+noble/curves provider, MemoryStorage
- M2: X3DH key agreement (identity keys, signed prekeys, one-time
prekeys, bundle processing for both initiator and responder)
- M3: Double Ratchet (symmetric-key ratchet, DH ratchet, skipped
message key cache, out-of-order delivery, AAD-bound headers)
68 tests, 0 failures — including full integration test of
X3DH handshake → Double Ratchet conversation.
