feat(release): CI matrix, PyPI trusted-publishing pipeline, registry manifest, Docker fix

- ci.yml: ruff lint/format, Linux 3.11/3.12 tests + coverage, Windows mocked-COM leg, package build + clean-venv wheel smoke, Docker smoke, server.json schema validation
- release.yml: tag -> test gate -> tag/version check -> build -> PyPI trusted publishing (OIDC) -> GitHub Release
- pyproject: SPDX license, authors, keywords, classifiers, project URLs, autocad-mcp-pro console alias; version 1.4.0
- Dockerfile: ship engineering/ + version.py (image previously missed both -> engineering tools failed in containers); healthcheck imports engineering
- server.json: MCP registry manifest (io.github.u-c4n/autocad-mcp, pypi package)
- docs/RELEASE-DISTRIBUTION.md: one-time owner actions (PyPI trusted publisher, mcp-publisher login) + directory submissions runbook
