 With the default `CliProgram::Resolve`, `Client::start()` resolves the CLI in this order: an explicit `CliProgram::Path(path)`, the `COPILOT_CLI_PATH` env var, then the bundled CLI that was embedded at build time. There is no PATH scanning — if you've opted out of bundling (`default-features = false`) you must supply either `CliProgram::Path` or `COPILOT_CLI_PATH`.
