fix(sdk): add Regtest support to trusted context provider activation height

[QuantumExplorer]

Issue Being Fixed

Nightly "Packages functional tests" fail with:

Proof verification error: Context provider error: Unsupported network

Root Cause

get_platform_activation_height() in rs-sdk-trusted-context-provider/src/provider.rs only handles Mainnet, Testnet, and Devnet. The functional tests run on a local regtest network, which hits the _ wildcard and returns an error.

What was changed

Added Network::Regtest to the Devnet match arm with activation height 1 (same as Devnet — platform activates at genesis on local/test networks).

- Network::Devnet => Ok(1),        // Devnet activation height
+ Network::Devnet | Network::Regtest => Ok(1), // Devnet/Regtest activation height

Breaking Changes

None. Previously Regtest always errored; now it works.

• Bug Fixes
  • Fixed support for Regtest network in the SDK, which previously resulted in an error. Regtest now properly uses the same activation height as the development network.

Walkthrough

The get_platform_activation_height function has been updated to treat Network::Regtest identically to Network::Devnet, returning an activation height of 1 instead of triggering an unsupported network error.

🐰 A test net's friend now finds its place,
Regtest hops with Devnet's grace,
One activation height they share,
No more unsupported despair! ✨
