/**

* Merges the three sources of dw connection settings — explicit

* command-line flags, environment variables, and named profiles —

* into a single resolved connection descriptor.

* Precedence (highest wins):

* 1. Command-line flag (`--server`, `--namespace`, `--token`).

* 2. Environment variable (DURABLE_WORKFLOW_SERVER_URL / _NAMESPACE / _AUTH_TOKEN).

* 3. Named profile (selected via `--env`, `DW_ENV`, or `current_env`).

* 4. Built-in default (server=http://localhost:8080, namespace=default,

* no token, TLS verification on).

* Profile selection rules (hard-fail branch of the feature):

* - `--env <name>` → hard error if profile does not exist.

* - `DW_ENV` env var → hard error if profile does not exist.

* - `current_env` in config → hard error if profile does not exist (the

* user explicitly set it with `dw env:use`; a missing profile means

* the config has drifted and silent fallback would hide the problem).

* - No selection signal → no profile applied; env/defaults win.

* The resolver never writes to disk. It simply reads the store and

* produces a ResolvedConnection the ServerClient can consume.
