test_harness_cli_run.py -- `ctx run` / `ctx resume` / `ctx sessions` CLI.
Every test mocks LiteLLM and (when needed) the MCP router so no real
subprocess or network happens. The goal is pinning:
* argv parsing for all 3 subcommands
* provider key-env auto-detection
* MCP spec parser (preset vs explicit)
* session-start metadata capture
* exit codes
* stdout / stderr separation (--quiet, --json)
* resume round-trip
Real-provider smoke lives in an integration-marked suite we'll add
once the full H1-H7 stack is proven on a live model.
