feat: POA/Manifest Ghostcloud

[fmorency]

This pull request introduces several significant improvements to the build system, code coverage, simulation tooling, and generated gRPC code for the project. The most notable changes include a major overhaul of the Makefile to enhance build, test, and simulation workflows, updates to the Go version and CI configuration, and the addition of new gRPC service files. Below are the most important changes grouped by theme:

Build System and CI Enhancements

• Overhauled the Makefile to add advanced build flags, dynamic versioning, improved build tag handling, and new targets for installation, protobuf generation, and simulation. The coverage workflow now merges simulation and unit test coverage for more accurate reporting. Obsolete or redundant targets (like nancy) were removed, and the golangci-lint version was updated. [1] [2] [3] [4]
• Updated the Go version in .circleci/config.yml from 1.22 to 1.23.12 and commented out the security job in both the jobs and workflows sections, likely to address compatibility or performance issues. [1] [2] [3]

Test Coverage and Simulation

• Improved coverage handling by instrumenting simulation tests, merging coverage data from simulation and unit/e2e tests, and generating both text and HTML reports. Added new .coverageignore patterns for coverage filtering. [1] [2]
• Added comprehensive simulation targets to the Makefile for running full app simulations, import/export, after-import, and determinism tests, with options for random seeds and parameterization.

Generated gRPC Code

• Added new generated gRPC client and server code for the Query and Msg services in api/liftedinit/ghostcloud/v1/query_grpc.pb.go and api/liftedinit/ghostcloud/v1/tx_grpc.pb.go, respectively. These provide type-safe interfaces for interacting with the Ghostcloud module over gRPC. [1] [2]

These changes collectively modernize the build and test infrastructure, improve developer productivity, and lay the groundwork for more robust service integrations.

Depends on #68

Pull Request Overview

This pull request implements significant refactoring to migrate the ghostcloud module from the legacy Cosmos SDK parameter store to the modern collections framework, while also updating generated protobuf files to use a new namespace structure. The changes improve code maintainability, type safety, and align with current Cosmos SDK best practices.

• Migrates parameter storage from x/params to collections framework for better type safety and performance
• Updates protobuf namespace from ghostcloud.ghostcloud to liftedinit.ghostcloud.v1 for better organization
• Refactors simulation code to use modern patterns and removes deprecated helper functions
