#253 docs: delete the stale 'a later slice adds install-hooks' sentence from hook docstrings

[Anonymous]

Originally created by: fu351

The docstrings for doberman hook pre and doberman hook post (in src/doberman/cli/main.py) still say a later slice will add doberman install-hooks - but install-hooks has existed in the same file for a while. A UX review flagged these as the kind of stale sentence that quietly erodes trust in the rest of the help text.

Task: delete the outdated sentence from both docstrings. Check hook openclaw for the same phrasing while you're there.

Done when: doberman hook pre --help (and post) no longer promise a feature that already shipped, and CI is green. No test changes expected - this is help text only.
