v0.2.0 — Wiki Automation Layer

v0.2.0 — Wiki Automation Layer

This release adds a complete automation layer for wiki maintenance and
raw source ingestion, and brings the Russian wiki layer to full lint-clean
status.

New skills

• docs/INGEST-SKILL.md — agent prompt for adding raw source material:
  fetches or accepts pasted content, classifies subdirectory, cleans body,
  builds frontmatter, runs duplicate checks, reports series detection
• docs/WIKI-SKILL.md — agent prompt for wiki page generation:
  Mode A (new ingest: raw/ → both wiki layers) and Mode B (update: revise
  existing pages when source changes)
• docs/ENHANCE-SKILL.md — single-page polish skill replacing
  PAGE-ENHANCEMENT-STANDARD.md: mechanical scan, frontmatter standardization,
  wikilink enrichment via link maps, content quality audit, lint gate

New scripts (tools/)

• check_duplicate.py — duplicate URL and slug detection before ingest
• derive_slug.py — filename slug normalization from URL
• check_series.py — series membership detection for raw/ files
• build_link_map.py — generates docs/link-map-en.md and
  docs/link-map-ru.md; agents read these instead of scanning directory trees
• check_parity.py — checks whether a slug exists in both wiki layers

Generated files

• docs/link-map-en.md and docs/link-map-ru.md — wikilink target maps
  for both layers; regenerate with python3 tools/build_link_map.py

Source policy

• raw/ now accepts Bitcoin-only sources beyond 21ideas.org — BIPs,
  Satoshi writings, established Bitcoin-only authors and publications
• Full tier list in docs/CONTRIBUTING.md; contributor prompt template
  added for Track 2 (EN + RU website versions)

Wiki content

• wiki-ru/: all 76 pages lint-clean (0 mechanical issues)
• wiki-en/philosophy/overview.md: first EN page enhanced with
  ENHANCE-SKILL.md — canonical frontmatter, wikilinks, reviewed field

Superseded

• docs/PAGE-ENHANCEMENT-STANDARD.md — replaced by ENHANCE-SKILL.md;
  kept for historical reference with superseded notice

Pending (v0.3.0 candidates)

• wiki-en/ full enhancement pass
• build_link_map.py integration into CI/deploy workflow
• INGEST-SKILL.md and WIKI-SKILL.md production testing
