v1.0.0, the public CLI release

What changed for looot customers in v1.0.0.

The first public release. npm install -g looot installs looot 1.0.0: browser sign-in with nothing to copy by hand, browsing the catalog with no account, one-line errors, typed errors on MCP, catalog listings that only offer what can actually run, and this documentation site. Verified with a fresh, unassisted customer test. Full details are in the v1.0.1 notes, released the same day from that test’s findings.
