feat: remove llms-full.txt references from agent directives

[mvvmm]

Summary

Removes llms-full.txt references from agent-facing directives. The file is intended for humans to point agents at in specific cases (offline indexing, bulk vectorization) — not for live agents to fetch autonomously.

Changes:

• AgentDirective.astro — removes the sentence directing agents to product and global llms-full.txt endpoints
• src/pages/llms.txt.ts — removes the llms-full.txt blockquote line from the global llms.txt
• src/pages/[...product]/llms.txt.ts — removes the llms-full.txt blockquote line from per-product llms.txt files

Human-facing documentation describing llms-full.txt (in docs-for-agents/index.mdx, prompting.mdx, and the style guide partial) is unchanged.

PR Review Summary

No issues found. The PR cleanly removes llms-full.txt references from three agent-facing files (AgentDirective.astro, src/pages/llms.txt.ts, and src/pages/[...product]/llms.txt.ts) without affecting human-facing documentation. All validation checks pass:

• pnpm run check — 0 errors
• pnpm run lint — clean
• pnpm run format:core:check — clean

The change is well-scoped and the implementation is correct. No inline suggestions needed.
