#267 feat(cli): rename the SessionStart panel to session-summary, keep dashboard as alias

[Anonymous]

Originally created by: fu351

Summary

• doberman dashboard is renamed session-summary - the old name collided with doberman dash (the web dashboard) and misdescribed a print-and-exit panel.
• dashboard survives as a hidden, permanent alias: existing installs' settings.json invoke that literal string at SessionStart, and breaking it breaks session start.
• install-hooks writes doberman session-summary going forward; remove_doberman_hooks recognizes and removes both old- and new-style SessionStart groups, so no install is left stranded on either name.
• docs/SETUP.md updated; README had no references to the old name.

Tests

• session-summary appears in --help; dashboard is hidden from it
• Both invocations print the panel and exit 0
• Fresh merge_doberman_hooks writes the new command string
• remove_doberman_hooks strips a legacy doberman dashboard group
• ruff / lint-imports (2 contracts kept) / targeted pytest green locally

Repo: core. No enterprise references; CLI command registration and hook-string plumbing only.

Part of the 2026-08-05 UX fix wave (audit: two commands both named "dashboard" was the top findability confusion).
