fix(ci): exclude .git from rsync --delete in sync-docs

rsync --delete removes everything in the destination that is absent from
the source. sencho/docs/ has no .git directory, so rsync was deleting
sencho-docs/.git/ on every run. The commit step then had no git repo to
work with, giving 'fatal: not in a git directory'.

Fix: add --exclude='.git' to the rsync invocation.

 ### Fixed
 - fix(ci): `update-screenshots` — add `pull-requests: write` permission and switch both `actions/checkout` and `peter-evans/create-pull-request` from `GITHUB_TOKEN` to `DOCS_REPO_TOKEN` (PAT with `repo` scope); `GITHUB_TOKEN` is blocked from creating PRs against protected branches
+- fix(ci): `sync-docs` — add `--exclude='.git'` to the rsync step; `rsync --delete` was deleting the `.git` directory cloned in the previous step because it doesn't exist in the source (`sencho/docs/`), causing `fatal: not in a git directory` in the commit step
 - fix(ci): `sync-docs` — replace `actions/checkout` + init fallback with a single controlled `git clone || git init` bash step; `actions/checkout@v4` leaves a `.git` in a broken state on empty repos, which the `[ ! -d .git ]` guard missed, causing `fatal: not in a git directory` in the commit step; also drop now-unnecessary `--global safe.directory` config
