feat: added restrict_relay option for local mode

[petruki]

This pull request introduces a new feature to restrict the use of relay when running in local mode, controlled by a new restrict_relay option (defaulting to True). The change updates the client context, Switcher behavior, resolver logic, and documentation, and adds tests to verify the new behavior.

Restrict Relay Feature:

• Added a new restrict_relay option to ContextOptions (default: True), which restricts the use of relay when using local snapshots. This is now part of the client context and is documented in the README. [1] [2] [3] [4] [5]
• Updated the Switcher class to include a .restrict_relay() method, allowing per-instance override of the relay restriction. The client now initializes Switcher instances with the context's restrict_relay value. [1] [2] [3]
• Modified the resolver logic to disable configs with relay enabled when restrict_relay is True. Added a helper to check if relay is enabled for a config. [1] [2]

Testing & Utilities:

• Added new tests to verify that relay restriction works as expected and can be overridden. Updated test helpers to support the new option. [1] [2] [3]
