Nuno Duque Nunes 14d2a78b78 feat: command mixin system, --json for list/inspect, tests
- core/command_mixins.sh: mixin infrastructure with auto-loader
- core/mixins/json_output.mixin.sh, no_color.mixin.sh
- commands/mixins/MIXIN_TEMPLATE.mixin.sh
- command::run: mixin preprocess with nameref, empty array guard
- list --json, inspect --json: structured JSON with envelope
- json::envelope, json::error_envelope
- tests: json output unit tests, group purge-stale, logs clean
