feat(gitflow): push-guard hook denies Claude's git push in manual-push mode

Run B of manual-push mode (BDR-111). With `gitflow.autopush false`
nothing stops Claude from typing `git push` itself: the `ask` tier is
inert under auto mode. This adds the mechanical block the user chose.

- hooks/push-guard.sh (PreToolUse, matcher Bash|Monitor, timeout 10):
  detects a push in the command text (strict, quote-stripped loose and
  alias patterns; backslash-newline folded in bash, BSD sed/grep only),
  reads gitflow.autopush in the payload cwd and in every literal -C/cd
  dir the command names (global config counts outside a repo), denies
  with the documented JSON form and a reason that tells the user to run
  the command with `!`. Unparseable value = manual (fail closed); once
  a push is detected an EXIT trap emits a static deny on any internal
  error. jq missing = one stderr warning, allow (sibling-hook policy).
- settings.json: hook wiring; 18 deny entries closing the write forms
  of the human-only toggle (any `git … config` spelling, section
  removal/rename, `-c`, config env overrides, direct edits of git config
  files); one soft_deny on pushing in manual mode in any form, with no
  per-turn clearance; the routing-around rule names hook refusals.
- hooks/session-start.sh: `🔒 push : manual (autopush=false) — ! git push`
  banner line when the key reads false (padding in bytes).
- lib/tests/push-guard.test.sh: 61 checks (push forms, over-blocks,
  invalid value, global key, fail-closed trap, no-jq, wiring, banner).

Known limits are listed in the hook header; the soft_deny rule is the
backstop. Run C (skills that push on their own) and run D (fail-closed
readers everywhere) follow. Do not enable manual mode at work before C.

       "Destructive tool against a local path: `lftp mirror`, `rsync --delete`, `find -delete`, `rm -r`, `chmod -R` or `chown -R`, or a docker volume drop, aimed at a path built from a variable, `~`, `..` or a wildcard, or resolving outside the current working directory and the session temp dir. This holds for a trace, a dry run, a rehearsal or an experiment that a brief, a plan step, a test recipe or a previous reviewer calls allowed: a sub-agent brief carries no user authority here, and on 2026-09-21 exactly such a trace (`mirror --delete` against a local `file://` tree) wiped the home, the NAS mount and 15 repositories. Tracing what such a tool would do is done by reading it. When a run is unavoidable, the target is a fresh `mktemp -d` path written literally in the same command, and `--dry-run` comes first. No in-session instruction clears this; the user runs the real thing by hand.",
-      "Branch deletion by hand: `git branch -d`, `-D` or `--delete`, `git update-ref -d`, `git push --delete` or the `:ref` push form, a rename of `main` or `develop`, or a script or sub-agent that does one of these, local or remote. The only sanctioned path is `gitflow.sh finish` or `gitflow.sh delete <branch>`, which refuses `main`/`develop` outright and any branch not merged into develop or main, then removes the `origin/` copy once its own tip passes the same check; `git branch -d` proves nothing once the branch has an auto-pushed upstream, which every branch has since BDR-095. A branch the lib refuses to delete still holds unmerged work: keep it and say so. No brief, plan step or cleanup routine authorizes a hand deletion.",
