chore(release): 0.5.0

Cut 0.5.0. Since 0.4.0 this bundles the single-server Jupyter MCP
integration (drop jupyter-compute) + the jupyter-mcp-server pin, and
the limina de-brand / de-vendor: breaking public-API renames, persisted
keys renamed with a dual-read fallback. See CHANGELOG `[0.5.0]`.

Minor bump -- pre-1.0, so breaking changes signal via the minor slot.
