v0.9.0-beta — /docs/llms.txt (LLM-friendly docs export)

Added

• /docs/llms.txt + /docs/llms-full.txt — the docs, LLM-friendly. An llms.txt export: llms.txt is a curated Markdown map (a section per public collection, its nav tree as a link list); llms-full.txt is every public doc's plain text in one file — ideal for feeding a language model the whole docs site cheaply.
• Regenerated on every index rebuild (Docs_Model_Docs::rebuildIndex → _writeLlms), cached per-server in var/docs-llms/ (a build artifact, never committed), and served as text/plain routes off the docs surface.
• URLs honor an admin /help retarget and become absolute when tiger.site.url is set, else site-relative.
• Sibling to the app-wide /llms.txt that TigerSEO serves (which links here).
