#266 fix(cli): setup wizard re-prompts instead of dying, explains what it asks

Summary

• A mistyped mode in the interactive wizard now warns and re-prompts instead of exiting and discarding every answer so far. The --mode flag path keeps its hard usage error (exit 2), so scripts see no change.
• The advanced-tuning step prints a plain-English line above each dimension prompt (DIMENSION_DESCRIPTIONS, same pattern as MODE_DESCRIPTIONS).
• The "agent profile" question is gone. It collected an answer and discarded it - runtime inference already covers app type - so it was pure cost at the most attention-critical moment of onboarding.
• Fixed an en-dash in parse_mode_choice's error text (choose 1-4), which the re-prompt loop now surfaces on a cp1252 console.

Tests

• test_setup_reprompts_on_bad_mode - typo then valid answer completes setup, warning shown
• test_yes_mode_invalid_exits_nonzero tightened to assert exit code 2 on the flag path
• Profile-absence assertions in every interactive flow
• test_setup_explains_each_tuned_dimension - each description precedes its prompt; dict order matches DIMENSIONS
• ruff check / ruff format --check / lint-imports / targeted pytest green locally

Repo: core. No enterprise references; wizard and helpers only - no decision-engine, auth, or redaction changes.

Part of the 2026-08-05 UX fix wave (critique: the wizard failed hard on a typo and asked for data it discarded).
