Pull request overview

This PR updates the repository’s CLI documentation and example workers to use the new Endpoint API (replacing @remote + LiveServerless/LB resource configs), aligning the examples with the upstream flash migration referenced in the PR description.

Changes:

• Migrates docs and examples from @remote(...) + LiveServerless/LB configs to @Endpoint(...) and Endpoint(...).get()/.post() route decorators.
• Updates autoscaling/resource configuration examples to the new parameter names (e.g., workers=(min, max), idle_timeout, scaler_type, scaler_value).
• Refreshes repository-level docs (README/CONTRIBUTING/CLI reference) to describe the new endpoint patterns (QB vs LB).
