feat(skill): set repo-local pull.rebase policy

pulling-before-work 1.0.1 -> 1.1.0: step 1b ensures repo-local
pull.rebase=true + pull.ff=only (set-if-absent) so manual pulls never
create merge commits, matching snolla baseline. Skill's own pull stays
--ff-only (aborts on divergence, never leaves repo mid-rebase).

 If the command fails or prints anything other than `true` → **exit silently, no chat output.** This is the not-a-git-repo case; the skill must not be noisy in random folders.
 
+### 1b. Ensure the repo's local pull policy (set-if-absent)

+```bash
+git config --local --get pull.rebase >/dev/null 2>&1 || git config --local pull.rebase true
+git config --local --get pull.ff >/dev/null 2>&1 || git config --local pull.ff only

+
+Sets the repo-local pull policy to the snolla baseline: plain `git pull` rebases instead of creating a merge commit (`pull.rebase=true`), and the merge path refuses non-fast-forwards (`pull.ff=only`). **Set-if-absent only** — an explicit local override the user wrote is never clobbered. Silent: no chat output, idempotent, works in dirty trees. Git config is untracked, so this never dirties `git status`. The skill's own pull below still uses `--ff-only` on purpose: a silent session-start pull never leaves the repo mid-rebase; divergence is always resolved by the human.
