Runtime Release Controls for Any-Language Repositories

Purpose

Introduce runtime release controls so merging and deploying code does not automatically expose unfinished or risky behavior to users.

In a deployless workflow:

• deployment moves code into the runtime
• release exposes behavior
• release can be changed without a new deploy when practical
• risky behavior has a kill switch
• flags are observable, testable, owned, and eventually removed

Control types

Choose one or more based on the repo's architecture.
