anoracleofra-code 39cc5d2e7c fix: compile privacy-core Rust library in Docker backend image
The MLS gate encryption system requires libprivacy_core.so — a Rust
shared library that was only compiled locally on the dev machine.
Docker users got "active gate identity is not mapped into the MLS
group" because the library was never built or included in the image.

Add a multi-stage Docker build:
- Stage 1: rust:1.87-slim-bookworm compiles privacy-core to .so
- Stage 2: copies libprivacy_core.so into the Python backend image
- Set PRIVACY_CORE_LIB env var so Python finds the library

Also track the privacy-core Rust source (Cargo.toml, Cargo.lock,
src/lib.rs) in git — they were previously untracked, which is why
the Docker build never had access to them.

Add root .dockerignore to exclude build caches and large directories
from the Docker build context.
