feat(tutorial): print next steps after a verified run

[abrichr]

Why

openadapt quickstart (flagship repo) delegates to this repo's tutorial. Roughly 52 people a day install openadapt, and today the tutorial ends in silence right after printing the VERIFIED receipt: zero links, zero next step, at the moment of peak intent.

What

After the receipt paths, on the plain VERIFIED path only, the CLI now prints:

That run made no model call and sent nothing off this computer.
  What it proves        https://openadapt.ai/execute
  Run it on your work   https://openadapt.ai/qualify

• The three URLs are exactly the ones the flagship OpenAdapt README already uses, so every surface points at the same destinations.
• _next_steps_block() is a small pure function in openadapt_flow/tutorial.py; _cmd_tutorial prints it with the same plain-print mechanism as the surrounding summary.
• Verified-path only: --break-it runs end on their own narrative, and non-VERIFIED runs keep ending on their evidence -- the block belongs to the success rail, mirroring the receipt rule.

Tests

tests/test_cli_tutorial_next_steps.py mirrors the browser-free pattern of tests/test_cli_tutorial_break_it.py (fake run_tutorial, assert on captured CLI output): the block carries the three URLs, is printed after the receipt on the VERIFIED path, and is absent on --break-it and non-VERIFIED paths. ci.yml untouched.
