[AAASM-4343] 📝 (docs): update repo URL references after prefix rename

[Chisanan232]

What

Cosmetic sweep of stale GitHub repo URLs in this repo's docs after the org-wide agent-assembly- prefix rename. Rewrites ai-agent-assembly/agent-assembly-examples -> ai-agent-assembly/examples across the README and docs/examples/* (17 files, links only).

Why

Eight org repos were renamed to drop the redundant agent-assembly- prefix. GitHub already 301-redirects the old URLs, so nothing is broken — this is purely cosmetic cleanup so live docs point at the canonical new paths.

How to verify

grep -rn "ai-agent-assembly/agent-assembly-examples" returns nothing; the bare agent-assembly core monorepo link and agent-assembly-spec are intentionally left untouched (not renamed). versioned_docs/versioned_sidebars and historical CHANGELOG entries were intentionally excluded — the redirect covers those and they are point-in-time snapshots.

🤖 Claude Code — automated review (AAASM-4343)

Verdict: ✅ ready for approval & merge (pending required Pioneer approval).

Scope vs ticket AAASM-4343 — in scope. Cosmetic sweep of stale ai-agent-assembly/agent-assembly-* (+ inner-document) repo-URL references to the new bare names after the org-wide prefix rename. Frozen versioned_docs/ snapshots and historical CHANGELOG/release entries were intentionally left to GitHub's 301-redirect. Bare agent-assembly (core) and agent-assembly-spec (archived) untouched. agent-assembly-enterprise kept its name (rolled back) and its refs were reverted here where applicable.

Side effects on existing behavior — none. %CODE_NOTE%
