SystemsLab 150.0.0

Added

• The context and experiment pages now auto-refresh in place as experiments progress, jobs change state, and artifacts upload, instead of requiring a full page reload.

Fixed

• Host tag templates in TOML experiment specs are now substituted correctly. Previously placeholders like {VAR} in job-level host tags were passed through literally instead of being replaced with the matching param or matrix value, so jobs tagged with templated expressions failed to match any host.
• The mcp proxy command no longer fails with auth errors after about an hour of use. The proxy previously loaded its OAuth token once at startup as a static string; it now uses the shared OAuth middleware that auto-refreshes tokens 10 minutes before expiry, matching the rest of the CLI.
