Pull request overview

Adds first-class llms.txt generation to YiiPress builds, controlled by a new default-on llms_txt site config option, and documents the feature.

Changes:

• Introduces SiteConfig::$llmsTxt plus YAML parsing support (llms_txt, default true) and a unit test to ensure it can be disabled.
• Adds LlmsTxtGenerator (with unit tests) and wires it into BuildCommand output + dry-run output listing.
• Updates documentation and roadmap to reflect the new build artifact and configuration option.
