feat: bilingual role SOP packs — 66 new skills, knowledge library, 4 role loops

[minhnv0807]

Four commits. The bulk is the latest one: four role-based standard-operating-procedure packs in both editions, taking the library from 72 to 138 skills, plus a foundation knowledge library and the workflows that tie them together. The earlier three commits add the growth/AI-Marketing-OS skills and README diagram work.

What this adds

33 Vietnamese skills (skills/vi/35-67)

Pack	Skills	Covers
Content system	35-40	Brand voice → content brief → organic caption → community seeding → content audit → next content plan
Design production	41-50	Campaign asset list → image/carousel/video/design-tool briefs → brand guideline → design review → quick visual brief → HTML email → asset resize
Performance ops	51-57	Audience research → account structure → tracking setup → media plan → scaling → retargeting → next ads plan
Leader ops	58-67	Positioning → GTM → launch playbook → budget planning → marketing review → retrospective → team brief → performance review → crisis playbook → vendor brief

Each skill is a full operating procedure — steps, required inputs, decision rules, quality gates, timelines — not a single prompt. Example: 54-media-plan carries the reverse-math from revenue to max CPL to budget with the 30/50/15/5 split; 55-scaling-ads has a 7-condition gate before scaling and a learning-phase reset risk table.

33 Global skills (skills/en/35-67 *-global)

Adaptations, not translations. Frameworks and process logic carry over unchanged. What changes: currency rebased to USD against references/benchmarks-global.md, channels swapped to the global stack (Klaviyo/Mailchimp instead of Zalo OA, Shopify/Amazon instead of Shopee/Lazada, Meta US/EU instead of Facebook VN), and compliance moved to FTC, GDPR, CCPA and CAN-SPAM.

Community seeding was rewritten, not localized. Three tactics in the Vietnamese version do not survive US/EU regulation and were removed rather than translated:

• Persona accounts → astroturfing under every major platform's rules
• Brand-written customer reviews → FTC 16 CFR Part 465 carries civil penalties
• Staged "looking for recommendations" threads answered by your own accounts → conversation manipulation

Replaced with a named-participant roster (real team members, affiliation visible), permission-backed customer story amplification, and disclosed answers in existing threads, at Reddit's 9:1 value-to-promotion norm.

No invented numbers. Where a Vietnamese threshold had no global equivalent in the benchmark file, it became a relative rule with the gap stated in-file — minimum ad set budget is now a derived formula (50 conversions × target CPA) / 7 rather than a currency conversion, and CTR cells for platforms without a repo median read "use account history" instead of a guess.

Also added

• knowledge/ — 24 foundation and implementation files, sized for upload as context into role-based AI projects
• agents/design-producer.md — sixth agent, owns the visual production pipeline
• 4 VN workflows — content-engine, performance-loop, design-pipeline, leader-cadence
• references/marketing-templates-library.md — structures of 28 operational templates, each mapped to the skill that regenerates it
• references/ai-tool-orchestration.md — multi-tool AI workflow for marketers

Changed

• 17 existing skills enriched with SOP-level detail — new sections only, no structural breaks
• benchmarks-vietnam.md extended — frequency thresholds, TikTok VTR, Facebook Group and Instagram organic rates, warn-vs-kill thresholds, target-relative scale/pause/test rules, CPO and ROAS by industry, B2B benchmarks
• Progressive disclosure applied to the 9 skills over the 500-line spec guideline — lookup tables and long templates moved into per-skill references/, nothing removed
• marketplace.json 72 → 138 skills, version 3.6.0

Fixed

• Stale reference paths skills/references/ → skills/vi/references/ in 12 places (folder moved in v3.0.0, links were never updated)
• .gitignore covered outputs/ but the real folder is output/, so client deliverables were sitting untracked-but-visible and one git add -A away from a public repo

Test plan

• validate-skills.ps1 → 89 passed, 0 issues; all 66 new skills PASS with no warnings
• Every related: entry in the 66 new skills resolves to an existing skill folder
• All 138 marketplace.json paths exist and contain SKILL.md
• No skill exceeds the 500-line guideline; content preserved across every split (verified by line-count reconciliation, e.g. skill 11: 605 → 428 + 221 in references)
• Markdown links in READMEs and new docs resolve
• install.sh and install.ps1 syntax valid; both now copy knowledge/
• Repo-wide grep confirms no source-author attribution remains
• Reviewer: confirm the Global benchmark figures match your read of references/benchmarks-global.md
• Reviewer: spot-check two or three Global skills for tone — they should read as native English, not translated

Merge state

GitHub reports the branch as mergeable with no conflicts against master, including the two commits master has that this branch does not (63cf44d, c30a009).
