fix(marketing-plan): address review findings from codex + local audit

Resolves 12 issues found during comprehensive review:

Spec compliance:
- Trim description from 1025 to 963 chars (was over 1024 limit)
- Drop non-standard top-level version field (VERSIONS.md tracks repo-wide)

Cross-marketplace clarity:
- Note that audit-marketing/positioning live in adjacent cf-skills repo
- Document optional external skills in ops-stack-mapping (typefully, etc.)

Idea cross-reference fixes:
- Correct Activation count (7 -> 8) and Acquisition count (88 -> 116)
- Rename "ideas" to "entries" for accurate row vs unique-idea distinction
- Add "How to read this doc" legend explaining 139 unique / 144 entries
- Remove #86 Lifetime Deals from Revenue (off-brand, kept in Skip note)
- Replace machine-local ~/.claude paths with repo-relative references

AARRR consistency:
- Move signups from Acquisition to Activation per signup boundary rule
- Add explicit signup-intent vs signup-completion distinction

Resumption + state model:
- Define progress.md schema (phase, current_section, plan_version, etc.)
- Replace ambiguous resume condition with explicit decision tree
- Protect finalized plans from silent overwrite (terminal state check)
- Mandate sections/01..13.md as canonical persisted artifacts
- Codify draft order (2..13 then 1, present 1..13)
- Align file layout in SKILL.md with methodology.md

Other:
- Add ## 1. Executive summary header to example-olo.md (was missing)
- Reconcile budget tier numbers ($5-15K canonical, was $5-10K elsewhere)
- Soften verification check to allow documented external skills

 This doc maps every marketing-skill and every relevant MCP/API integration to the AARRR stage(s) it primarily serves. It's the source for Section 11 of every plan.
 
+> **Note on scope.** Skills below are drawn from the broader Claude Code marketplace ecosystem — not all live in this `marketingskills` repo. Skills shown without a `:` prefix (e.g., `seo-audit`) are in this repo. Skills referenced from adjacent marketplaces (e.g., `cf-skills:audit-marketing`, `vercel:agent-browser`, `compound-engineering:diagram-maker`, `marketing-skills:typefully`) are optional — substitute equivalents if not installed. When a plan references a skill that isn't available, fall back to the underlying tactic and call it out in Section 13's open decisions.

 ## The thesis
 
 A small team + fCMO + agentic tooling = output of a 15–20-person traditional marketing org. The skills + MCPs encode workflows that previously required dedicated headcount per channel.
