Address independent review: plan 11

Read .orchestration/plan-11-review.md, pinned approved plan 11, current AGENTS.md, RTK, and applicable receiving-code-review/documentation skills. Verify both findings against current source before editing.

Make smallest documentation-only corrections within existing three-file scope:

• Remove unqualified attachment promise from changelog. Prefer saying users can paste a job description there; keep exact supported attachment details in guide where current MIME/direct-file qualifications already exist.
• Remove adjacent duplication of review/restore/rollback guidance in using-ai-agent.mdx. Keep concise workflow step and point to existing Review patches section, retaining full behavior explanation only once.

Preserve verified history, current provider capability boundary, isolated AI Draft behavior, no invented removal motive, and no promise of paid JSearch restoration. Run focused source probes, Markdown lint, relevant targeted tests if claims changed, link/diff/three-file scope gates. Add normal follow-up commit.

Write .orchestration/plan-11-review-fix.md with finding verification, exact commit/files, commands/results, skipped gates, and remaining risks. Do not push/open PR/merge/mutate issues/spawn subagents. Final response at most ten lines.
