Function dispatch 

pub async fn dispatch(
    product: &str,
    version: &str,
    args: Vec<String>,
    file_config: RawConfig,
) -> i32

Dispatch args (everything after argv[0]) and return the process exit code.

file_config is the agent’s own settings-file layer, sitting below the environment in precedence. Each agent stores settings differently — Claude Code uses .claude/<plugin>.local.md, Qwen and agy will use their own — so the format is the plugin’s business while the precedence is decided once, here. Pass RawConfig::default() for an agent with no settings file.

Exit codes are part of the contract with the launching agent: 0 success, 1 serve terminated with an error, 2 bad usage, 3 the log file could not be opened.

A bad or absent Ghidra CONFIGURATION is deliberately not among them: serve starts anyway and reports the problem on the first tool call, so that a host listing the tool schemas gets them on a machine with no Ghidra install.
