fix(release): publish runnable CLI and cache docs workers

[nick-csu]

Fixes the published CLI package and the intermittent demo Worker resource-limit failures.

• merge all bundled workspace runtime dependencies into the staged CLI package
• smoke-test a clean tarball install, commands, MCP generation, docs build, and docs start
• pre-render docs pages and expensive read-only API routes
• enable OpenNext static-asset cache interception and raise the Worker CPU ceiling
• verify the deployed demo with concurrent requests

Validated locally with formatting, lint, all package tests, a clean package smoke test, OpenNext build, and Wrangler dry-run.
