docs: harden template onboarding

[agentic-organization]

Summary

Hardens the mini-agi template so it is easier and safer for new organizations to adopt.

What changed

• Added onboarding docs:
  • docs/GETTING_STARTED.md
  • docs/CONFIGURATION.md
  • docs/OPERATING_LOOP.md
  • docs/PRIVACY_AND_DATA.md
  • docs/EXAMPLE_WALKTHROUGH.md
• Added reusable skills:
  • mini-agi-onboarding
  • source-watchlist-management
  • evidence-to-wiki-synthesis
  • privacy-redaction-review
  • template-release-audit
• Added .github/workflows/smoke.yml for template validation.
• Updated README, AGENTS, docs index, and skills index links.

Verification

• python3 -m json.tool data/sources/github-watchlist.json
• python3 -m json.tool data/sources/github-watchlist.example.json
• python3 -m json.tool package.json
• tools/search/build.sh
• node tools/search/search.js "github ingestion" --bm25-only
• node tools/ingestion/github-daily-ingest.js --dry-run --limit 3
• org-specific leak scan for prior source organization/project terms
• accidental secret-pattern scan with intentional documentation allowlist

Notes

The template remains organization-independent; the new docs and skills use only fictional example-* placeholders.

[agentic-organization]

Added the generalized ingestion pipeline implementation requested:

• standard stage contract documented in docs/INGESTION_PIPELINE.md
• generic manifest schema validator/listing tools under tools/pipeline/
• GitHub daily ingestion now emits manifest.json plus legacy run.json
• added --run-id support for stable cron/process IDs
• added ingestion-pipeline skill
• added pipeline tests and CI coverage for manifest validation

CI is passing.
