Fixes the flagship broken-lab findings: the prose claimed git behavior the shown commands didn't produce.

#2 M4 — commit the reviewed delete before the throwaway, so git restore . returns to a delete-containing checkpoint (was silently wiping the feature).
#3 M7 — the 'watch it break' demo now switches to an existing divergent branch, so the would be overwritten by checkout refusal actually fires (git switch -c carried edits over and exited 0).
#12 M7 Part C — show worktree isolation with commands that exist at that point; move clear/count to after they're added.
#4 M14 — recover with git revert HEAD (Module 12 precedes M14) so CI goes green; remove the incorrect restore/Module-2 attribution.

Dependency chain respected (no reset/revert introduced into M4/M7). All four reproduced and verified in throwaway repos on Git 2.53.0.

fix(modules-4,7,14): make the git demos/labs actually do what the prose claims 9835dba566

- M4 Part C now commits the reviewed `delete` change as the checkpoint, so
  Part D's `git restore .` returns to a delete-containing state (was wiping it).
- M7 'watch it break': switch to an existing divergent branch so the
  "would be overwritten by checkout" refusal actually fires (git switch -c never did).
- M7 Part C: demonstrate worktree isolation with existing add/list and distinct
  per-worktree data; move the new clear/count commands to after they exist.
- M14 Part C: recover with `git revert HEAD` (Module 12, which precedes M14) so
  CI legitimately goes green; drop the wrong "Module 2's safety net" attribution.
