fix(config.ts): revert OCO_GITPUSH to its original position in the config object for clarity

refactor(config.ts): rename configFromEnv to envConfig for better readability
refactor(gemini.ts): simplify client initialization in the Gemini constructor
test(config.test.ts): add test case to check overriding global config with null values in local .env
test(gemini.test.ts): update AI provider assignment to use OCO_AI_PROVIDER_ENUM for consistency
