feat(index): add openai/skills and affaan-m/ECC to curated skill index (#648, #649)

[luongnv89]

Summary

• Added 2 new skill repository sources to the curated index (openai/skills, affaan-m/ECC)
• Total new skills indexed: 331 (43 + 288)
• Catalog rebuilt: 77 repos, 6082 skills

New Repos

Repo	Skills	Description
openai/skills	43	Skills Catalog for Codex
affaan-m/ECC	288	Agent harness performance optimization system for Claude Code, Codex, Opencode, Cursor and beyond

Audit Summary

All indexed skills passed lightweight audit (name + description present). Eval scores and token counts populated for every skill entry. ECC repo contains 898 SKILL.md files upstream; ASM's discoverSkills pipeline (maxDepth 5 + name dedupe) indexes 288 canonical skills — matching the existing affaan-m/everything-claude-code index pattern.

Closes #648
Closes #649

Approach

Added both repos to data/skill-index-resources.json, ingested via the standard ingester pipeline, copied per-repo index JSON into data/skill-index/, and rebuilt catalog stats with npx tsx scripts/build-catalog.ts.

Decision Record

• Root cause: Both repositories were missing from the curated skill index, making their skills undiscoverable through ASM search and the catalog site.
• Options considered: Standard resources-entry + ingest + catalog rebuild pipeline (batch-compatible for issues Index missing skill repo: openai/skills (Skills Catalog for Codex) #648 and Index missing skill repo: affaan-m/ECC (agent harness performance optimization) #649).
• Options rejected: Full npm run preindex over all 77 repos — unnecessary; targeted ingest for the two new sources only.
• Selected option: Append both repos, ingest in order (openai/skills first, then affaan-m/ECC), rebuild catalog stats.
• Residual risk: ECC upstream has deeply nested skills beyond maxDepth 5 that are not indexed; documented in audit summary.
• Effort profile: full — large ECC index file (~1.6 MB), batch of two issues

Acceptance Criteria Verification

Criterion	Status	Evidence
Clone and audit openai/skills for valid agent skills	pass	43 skills discovered, all with name + description + evalSummary
Clone and audit affaan-m/ECC skill definitions	pass	288 skills indexed (ASM canonical set); all entries verified with eval data
Regenerate skill index with new repos included	pass	data/skill-index/openai_skills.json, data/skill-index/affaan-m_ECC.json
Rebuild catalog and verify entries appear	pass	website/repo-stats.json lists both repos; catalog build reports 77 repos, 6082 skills
Open PR with index changes for review	pass	This PR

Test Plan

• data/skill-index-resources.json is valid JSON with both new entries
• Index files generated in data/skill-index/
• npx tsx scripts/build-catalog.ts completed without errors
• CI=true npm test — 2689/2689 passed
• CI passes
