mcp: delete the ida-pro-mcp transport, supervisor, and mcp-only tests

The idalib worker is the only backend now, so remove the dead HTTP/supervisor
surface entirely (~2200 lines):

* deleted idatui/client.py (the IDAClient HTTP/JSON-RPC transport + session
  manager), idatui/tui.py (the old mcp TUI entry, superseded by launch.py),
  spawn.sh, and systemd/ (the supervisor unit).
* deleted the mcp-only tests (stress_client, smoke_client, test_keepalive,
  stress_paging, rpc_smoke, serverctl.sh, pane_smoke, test_domain) -- the worker
  pilot (tests/test_scenarios.py) supersedes them.
* migrated the tmux RPC harness (idatui/pane.py) to the worker: it spawns
  `idatui.launch <binary> --rpc <sock>` instead of the mcp `idatui.tui`, drops
  the supervisor auto-start/ensure machinery, and reaps our own worker
  (idatui/worker.py) instead of ida_pro_mcp.idalib_server. --db/--url/--no-
  ensure-server are gone; --open is required.
* __init__ / __main__ / domain no longer import client (exceptions come from
  errors.py, the domain client hint is WorkerClient); pyproject points both
  console scripts at idatui.launch; README + ida-tui header describe the
  worker-only flow.

What stays (by design): the ida_pro_mcp *package* (the worker reuses its @tool
functions in-process) and server/patch_server.py (the worker injects its custom
tools on startup). Verified: whole package imports + IdaTui constructs + pilot
lists 31 scenarios. The worker pilot (134 pass / 2 known flakes) is the E2E gate.
