fix(marketing-plan): strip references to internal-only audit-marketing and positioning skills

The marketing-plan skill was authored in an environment where the
internal `audit-marketing` and `positioning` skills (cf-skills repo,
not publicly installable) were available. Public users of this skill
would see 27 references to a skill they cannot install, plus an
explicit private-repo path.

Sweep across 7 files:

- `SKILL.md` frontmatter description rewritten to drop "see audit-marketing"
  and "see positioning"; replaced positioning reference with
  product-marketing (its public-skill equivalent for foundational
  positioning/ICP/voice capture)
- `SKILL.md` body: "Cross-references" and "Related skills" sections
  reorganized around skills that actually live in this repo
- `methodology.md` Step 1.5 rewritten — instead of "offer to run
  /audit-marketing," it now describes scoring from materials or
  ingesting a separately scored audit
- `current-state-rubric.md` intro rewritten — the rubric is now the
  source of truth for Section 3, not a derivative of audit-marketing.
  Removed cf-skills repo path. Removed the "Path A vs Path B" framing.
- `plan-template.md`, `ops-stack-mapping.md`, `client-types.md`,
  `example-quietude.md` updated to remove `audit-marketing` and
  `positioning` from skill lists

The rubric content itself (17 sections with scoring guides) was already
embedded in current-state-rubric.md, so external users have everything
they need to execute Section 3 of the plan.

validate-skills.sh: 43/43 passing. Description still 949 chars.

-If no audit has been run on this client AND the user wants a formal scored current-state, offer:
-> *"Want me to run `/audit-marketing {client-domain}` before we draft the plan? It produces a 17-section scored audit that becomes the foundation of Section 3 (Current State). Takes ~30–60 min of walking through sections together."*
+Use the 17-section rubric in `references/current-state-rubric.md` as your scoring lens. Two modes:
 
-If user agrees, run that skill. Resume here when done.
+- **From rich materials.** When the team has shared decks, prior content audits, an existing brand voice doc, recent positioning work, or a kickoff call transcript — score from those. Mark "scored from materials" in the section heading.
+- **From a separately scored audit.** If the team already has a scored current-state assessment (in any format), ingest those numbers directly. Don't redo the work.
 
-If user declines (common when fCMO already has rich context), use the rubric as a current-state *lens* against existing materials — faster, less rigorous, captured in `references/current-state-rubric.md`.
+Either way, the output is the scored 17-row table that becomes Section 3 of the plan, followed by a 2–4 sentence "shape interpretation" calling out where strengths and gaps cluster.
