feat(skills): bulk-mirror 40 marketing skills + migrate to canonical upstream (v6.51.0)

[sergei-aronsen]

Summary

Bulk skills-marketplace expansion. 40 marketing skills mirrored from the canonical upstream coreyhaines31/marketingskills (29.6k★, MIT). Active skills_pins jumps 23 → 61 — largest single skills shipment since v6.44.0.

Why

• coreyhaines31/marketingskills is the canonical upstream (29.6k★, MIT). The mysticaltech fork (currently sourced for 4 toolkit pins) is a 246★ downstream whose "pre-built .skill files" advantage does not apply inside the toolkit's raw-mirror model.
• The 38 new skills fill major gaps in the toolkit's solo-developer marketing surface: CRO (popups, paywalls, signup, onboarding), content (content-strategy, programmatic-seo, ai-seo, schema), acquisition (ads, cold-email, directory-submissions, free-tools), monetization (pricing, paywalls), retention (churn-prevention, emails, referrals), research (customer-research, competitor-profiling, competitors, marketing-psychology).

Added (38 new)

ab-testing, ad-creative, ads, ai-seo, analytics, aso, churn-prevention, co-marketing, cold-email, community-marketing, competitor-profiling, competitors, content-strategy, copy-editing, cro, customer-research, directory-submissions, emails, free-tools, image, launch, lead-magnets, marketing-ideas, marketing-psychology, onboarding, paywalls, popups, pricing, product-marketing, programmatic-seo, referrals, revops, sales-enablement, schema, signup, site-architecture, social, video.

Each skill mirror includes the full SKILL.md + references/*.md + evals/evals.json layout (157 total files across 40 skill dirs).

Migrated (2 — upstream re-anchor)

• copywriting: source mysticaltech/marketingskills → coreyhaines31/marketingskills. Mirror content + sha256 refreshed.
• seo-audit: same as above.

Retained (2 — distinct names)

• ab-test-setup keeps mysticaltech source; coreyhaines31 calls it ab-testing (renamed in fork). Both coexist.
• analytics-tracking keeps mysticaltech source; coreyhaines31 calls it analytics. Both coexist.

Lockstep

• manifest.version 6.50.0 → 6.51.0.
• 9 installer scripts TK_TOOLKIT_REF default bumped.
• templates/skills-catalog.json regenerated (23 → 61 entries).
• skills_pins_note active count 23 → 61.
• Mirror size: ~1.5 MB → ~6.7 MB.

Test plan

• make check — all gates pass (after scripts/generate-skills-catalog.sh regen)
• 40 sha256 hashes via scripts/lib/skill-checksum.sh match manifest entries
• python3 -c "import json; json.load(open('manifest.json'))" — JSON valid
• 157 files mirrored (40 skill dirs × avg 4 files)
• CI on GitHub Actions
• /update-toolkit smoke test pulls all 40 skills into ~/.claude/skills/
• Skills surface in Claude's discovery without naming collisions

Compatibility

• No breaking changes on the manifest schema or skills_marketplace install path.
• Soft breaking on content for users who depended on the exact prior copywriting or seo-audit text — the canonical-upstream content differs from the mysticaltech version. Behavior remains semantically equivalent.
