Restore the template and Worker agent instruction files and point them at the changelog

[zackbart]

#552 removed templates/node/AGENTS.md, its CLAUDE.md symlink, and examples/worker/AGENTS.md. That was a mistake: they are what an agent reads inside a generated deployment, where none of connecta's own documentation is in view. This restores them and everything that depended on them.

Restored

• The three files, byte-identical to before Cut the documentation to four guides and move provider rationale into code #552 apart from the audit fixes below.
• connecta init recreating the CLAUDE.md symlink (npm strips symlinks from a packed dependency), with the copy fallback where symlinks are disallowed.
• scripts/check-package.mjs asserting the packed template ships AGENTS.md and that a generated deployment has both files with CLAUDE.md a symlink.
• test/deployment-shapes.test.ts pinning the template inventory and the three hosted-MCP callback URIs in the Worker AGENTS.md.
• The pointers to them in templates/node/README.md, examples/worker/README.md, examples/worker/src/index.ts, and the root AGENTS.md.

Audit fixes

Every claim in both files was checked against the template and example source (executor: quickJsExecutor(), the typecheck and doctor scripts, CONNECTA_TOKEN, src/file-activity.ts, cloudflareAccessAuth(), the loader-only DynamicWorkerExecutor, CREDENTIAL_ENCRYPTION_KEY). Two were wrong:

• The template file sent upgraders to documentation/upgrading.md, which Cut the documentation to four guides and move provider rationale into code #552 deleted. It now says to bump the exact pin and read the changelog for every release in between, online or at node_modules/@zackbart/connecta/CHANGELOG.md, which does ship.
• The Worker file told a copied deployment to run npm run check:examples, a script that exists only in the connecta repository. It now names that for in-repo work and tsc --noEmit for a copy.

Also removes a stray blank line that split the template's bullet list, and drops the Unreleased changelog line announcing the removal, since the released behavior is unchanged.

npm run release:check passes locally: 119 files, 3267 tests passed, 37 skipped. The Docker container smoke was skipped locally and runs here.
