feat(humanizer): update action command templates [skip-docs]

Wave 5 Step 15. Threads --raw plumbing through all seven action
command templates and adds a shape test covering structural plumbing
plus help.md's plain-language vocabulary.

- commands/fix.md: --raw flag parsed; fix-plan rendering groups by
  userActionLanguage; humanized title/description/recommendation are
  rendered verbatim from the cross-referenced scan envelope.
- commands/rollback.md: terminology pass — "manifest" → "list of
  changes" in user-facing copy; the file name manifest.yaml is kept
  as the machine contract; --raw threaded through.
- commands/plan.md: --raw forwarded to the planner-agent's prompt;
  agent now instructed to group actions by userImpactCategory and
  lead with userActionLanguage; bash block added for flag parsing.
- commands/implement.md: --raw forwarded to the implementer-agent's
  prompt; progress-log lines now reference the humanized titles
  already present in the action plan.
- commands/cleanup.md: --raw accepted as no-op (cleanup is
  file-management only, no findings prose); bash block added.
- commands/help.md: full plain-language pass — "PreToolUse" and
  "frontmatter" jargon removed from user-facing copy; new
  vocabulary table surfaces the humanized userImpactCategory and
  userActionLanguage labels ("Configuration mistake", "Conflict",
  "Wasted tokens", "Missed opportunity", "Dead config" / "Fix this
  now", "Fix soon", "Fix when convenient", "Optional cleanup",
  "FYI"); --raw documented as global pass-through flag.
- commands/interview.md: --raw accepted as no-op; "unused hooks"
  question phrased as "unused automation that runs at specific
  events" in user-facing copy.

tests/commands/action-commands-shape.test.mjs (new, +6 tests, 780 → 786):
  - structural: bash block + Read tool + --raw/$ARGUMENTS plumbing
    across all 7 files
  - help.md vocabulary: ≥3 userImpactCategory labels and ≥3
    userActionLanguage phrases present
  - help.md jargon: no bare "PreToolUse" or "frontmatter" in copy
