Synapse v1.8.0 — Reliability & release quality

This release is about making Synapse safe to ship and hard to break. It adds a
comprehensive backend test suite, gates every release on those tests, validates
all installation paths in CI, and fixes an npm packaging-hygiene issue.

No breaking changes. Drop-in upgrade from 1.7.x.

🧪 Comprehensive test suite

A new backend/tests/ suite (321 tests) covers the full API surface and the
core flows end-to-end:

• Agent chat and agent chat stream (SSE)
• Orchestration chat and orchestration chat stream (SSE)
• /api/v1 (in-process) and /api/v2 (distributed) external APIs
• Every app route, plus auth, validation, backpressure (429/503), and adversarial
  edge cases (revoked keys, path traversal, malformed model output, oversized input)
• Real LLM calls are replaced by a deterministic fake, so the suite needs no API
  keys and no network
• Stress tests simulate 5–90s LLM latency under concurrent load, including the
  SSE streaming + reconnection path

🚦 Releases are now gated

• The full test suite must pass before anything publishes to PyPI, npm, or
  Docker Hub — a failing test aborts the release.
• Version consistency (pyproject.toml == package.json == tag) is enforced.
• The exact built wheel is installed and the CLI is smoke-run before upload.

🧰 Installation validated in CI

Every install path is now exercised automatically:

• pip (wheel + sdist, Python 3.11/3.12/3.13)
• npm (package contents + launcher)
• Docker image builds (Dockerfile, Dockerfile.backend, Dockerfile.worker)
  with a live API-server health check
• docker-compose config for the default, scale, and enterprise profiles
• A nightly job brings up the full stack and stress-tests it

📦 Packaging fix

• The npm package no longer risks shipping stale Python bytecode
  (__pycache__/*.pyc); a prepack step now cleans it and CI enforces it.
