[do not merge] test(solana): deploy gateway-event-cpi Gateway contract to solana-5

[nbayindirli]

Note

Updates solana-5 AxelarGateway address, switches event parsing to gas-service CPI, removes ITS CLI, bumps/introduces event-CPI/anchor dependencies, and adjusts upgrade docs to solana program deploy.

• Solana CLI / ITS:
  • Remove ITS CLI module: delete solana/src/its.rs and drop Its subcommands from solana/src/main.rs (instruction/query/build paths).
• Gateway:
  • Event parsing: gateway_event_stack::build_program_event_stack now uses parse_gas_service_log instead of parse_gateway_logs in solana/src/gateway.rs.
  • Dependencies: add event-cpi, event-cpi-macros, anchor-discriminators(-macros) to axelar-solana-gateway; adjust related crates.
• Gas Service:
  • Dependencies: add anchor-discriminators-macros to axelar-solana-gas-service.
• Config:
  • axelar-chains-config/info/devnet-amplifier.json: update solana-5 AxelarGateway.address and upgradeAuthority.
• Docs:
  • releases/solana/2025-09-GMP-upgrade-vanilla.md: change upgrade command to solana program deploy --program-id $PROGRAM_PDA $PROGRAM_PATH.
• Dependencies (Cargo.lock):
  • Introduce anchor-discriminators, event-cpi; remove/adjust some deps (e.g., event-utils), and bump several crate versions (e.g., mpl-token-metadata, num_cpus, openssl-src, socket2).

Summary

This PR implements a test deployment of a new Gateway contract variant called 'gateway-event-cpi' to the solana-5 devnet environment. The changes span three key areas:

1. Configuration Update: Updates the AxelarGateway contract address in the devnet-amplifier configuration from the old address to a newly deployed contract at gtwLmC1UUvmkVCN4NoXobHbLpQN2AZEZrWyqc7Q13QA. This configuration change maintains all other parameters like domain separator, connection type, and authority addresses while only updating the contract reference.

2. ITS Module Cleanup: Removes redundant parameters from multiple instruction function calls in the Solana ITS module. These changes affect functions for deploying interchain tokens, transferring operatorship, managing flow limiters, and handling minting operations. The removed parameters (like sender, proposer, accepter, adder, remover) were likely being passed to instruction functions that now derive these values automatically.

3. Event Parsing Modification: Switches the event parsing function from parse_gateway_logs to parse_gas_service_log in the gateway events query functionality. This change specifically targets gas service event parsing rather than general gateway event parsing, likely to accommodate the new contract's event emission patterns.

The changes appear to be part of testing a new Gateway contract implementation that focuses on Cross-Program Invocation (CPI) functionality with gas service event handling capabilities. The PR title explicitly states this is for testing purposes and should not be merged.

Filename	Score	Overview
axelar-chains-config/info/devnet-amplifier.json	3/5	Updates AxelarGateway contract address for solana-5 chain to new deployment

solana/src/gateway.rs	3/5	Switches event parsing from gateway logs to gas service logs

Confidence score: 3/5

• This PR appears to be a test deployment with moderate risk due to configuration inconsistencies
• Score reflects potential issues with incomplete configuration updates and functional changes to event parsing
• Pay close attention to the configuration file for potential inconsistencies with SolanaVotingVerifier references

logic: The gateway address change may require updating the corresponding SolanaVotingVerifier sourceGatewayAddress at line 1950 to maintain consistency between gateway and verifier configurations.

this is correct, we are going to need to deploy a new voting verifier
