e519ede9 - docs: less aggressive AI agent hint for an experimental API (#93811)

docs: less aggressive AI agent hint for an experimental API (#93811) The "AI agent hint" comment on the docs landing page (`docs/index.mdx`) tells every agent reading the docs on every task to export `unstable_instant` to fix slow client-side navigations. That's too aggressive for an experimental API — `unstable_instant` is `version: draft` and still reshaping (`unstable_prefetch` just split off in #92754). The instant-navigation guide already covers the API in measured language; agents working on slow-navigation tasks will find it there. <!-- NEXT_JS_LLM_PR -->
