Render an install command for the selected targets

When a user scaffolds this template with --targets portable, cursor, or codex, the generated README still tells them to install claude. A portable-only scaffold now has no npm installer bin at all, while cursor- and codex-only installer bins reject claude because generated host validation is restricted to built targets. The same hard-coded command appears in the mcp-server template, so the README should be rewritten from the selected targets or use a target-neutral explanation.

Useful? React with 👍 / 👎.

[ScriptedAlchemy]

Fixed in #397 (merged as d25a9c6). create-agent-bundle rewrites the scaffolded README install section per selected --targets: one npx <bin> install <host> line per installable host (claude/codex/cursor), and for portable-only scaffolds an explanation that no installer bin is generated plus the exact package.json bin entry to restore. Applies to both cli-tool and mcp-server templates; scaffold tests cover single-host, multi-host, and portable-only combinations.

[ScriptedAlchemy]

Landed after rebasing onto the main Verify repair from #328. Post-rebase local gates were authoritative and green: build; scaffold.test.ts 20/20; workspace typecheck; and focused lint with 0 warnings/errors. Admin-merged as af84c337025999980f829b7e1fc9806e40a9a8b7.
