v0.7.0: agent support, FMU interfaces and connections, restructured documentation - fmus signals: an FMU's interface (variables, units, quantities, required inputs, OSP groups) without downloading it - fmus connections: FMUs that could be connected to an FMU, through OSP group types or physical quantities, from searches, the cache, directories, fmufile.txt or a catalog; with variable pairs, unmatched required inputs and --need coverage - fmus search --catalog: search a generated catalog.json - fmus agent context, schema and install-skill, and fmus help --json: everything an AI agent or script needs, generated from the binary - Documented exit codes (2 usage, 3 not found, 4 auth, 5 network, 6 invalid content, 7 partial result) and JSON errors with --json; scripts that expected 1 for every failure need updating - Catalog connections: Generic OSP groups only match groups with as many variables - Shorter README with documentation pages under doc/; the CLI reference and annotation keys are generated from the binary
