#463 fix(cli): align hook dry-run with installed command

[Anonymous]

Originally created by: slegarraga

Closes [#429]

What

• Uses DASHBOARD_COMMAND in both install and uninstall dry-run previews so the displayed SessionStart command is the same one the installer writes.
• Adds regression coverage asserting the preview contains doberman session-summary and no longer mentions doberman dashboard.

Verification

• .venv/bin/pytest tests/unit/test_install_hooks.py — 44 passed.
• .venv/bin/pytest tests/unit -k 'install_hooks or cli_help or cli_encode_safe' — 117 passed, 1 skipped.
• .venv/bin/ruff check src tests — passed.
• .venv/bin/ruff format --check src/doberman/cli/main.py tests/unit/test_install_hooks.py — passed.

Merged, thanks @slegarraga! Importing DASHBOARD_COMMAND into the preview means the dry run can never drift from what the installer writes again, which was the whole bug. One thing on the landing. Your branch and [#472] both added an import at the same line in cli/main.py, so I merged main into a copy of your branch in our repo (land/pr463, [#493]) and resolved that one line. Your commits and authorship are untouched.

Thank you for handling the landing conflict so carefully and for preserving the commits and authorship. The landing branch was a thoughtful way to resolve the shared import anchor without disturbing either change. I really appreciate the detailed review — glad the shared constant now keeps preview and installation behavior aligned by construction!
