feat(solana): Make transceiver peers upgradable

[nvsriram]

Currently, the set_transceiver_peer instruction can only be called once since it uses init. This means if the transceiver peer needs to be modified, then the transceiver needs to be redeployed. This PR changes the set_transceiver_peer instruction to be init_if_needed so that we can update previously set transceiver peers.

This also adds unit tests for update_peer and update_transceiver_peer

📝 Walkthrough

Walkthrough

This pull request enables the mainnet feature flag across Solana build and test targets, modifies the account initialization constraint for transceiver peer accounts from init to init_if_needed, and adds comprehensive tests for peer and transceiver peer update functionality.

Changes

Cohort / File(s)	Summary
Build Configuration solana/Makefile	Updated cargo-build, cargo-test, and cargo-lint make targets to consistently include --features "mainnet" flag for compilation and linting steps.
Transceiver Peer Management Infrastructure solana/programs/ntt-transceiver/Cargo.toml, solana/programs/ntt-transceiver/src/wormhole/instructions/admin.rs	Updated anchor-lang dependency to enable init-if-needed feature and modified SetTransceiverPeer account constraint from init to init_if_needed to allow account creation if it doesn't already exist.
Admin Tests solana/programs/example-native-token-transfers/tests/admin.rs, solana/programs/ntt-transceiver/tests/admin.rs	Added new test utilities, imports, and async test functions (test_update_peer and test_update_transceiver_peer) to verify peer and transceiver peer configuration updates with on-chain account data validation.
Test Initialization solana/tests/anchor/anchor.test.ts	Added top-level registerDefinitions() and registerSolana() function calls to ensure required SDK definitions and Solana program registrations are initialized during test module setup.
