Release portable multiplayer merge in 0.2.0

[chenmingtang830]

Summary

• release Proofpress 0.2.0 with portable capsule DAGs and no-Git parallel merge
• keep parents for same-artifact lineage and ingredients for other-document sources
• make all 18 official Markdown documents portable and canonicalize discovery at proofpress@latest
• publish concise English documentation, FAQ, privacy boundaries, and agent workflows
• preserve the category position: “Proofpress makes intelligence compound”

Launch correctness

• npm-installed workflows consistently use npx --no-install proofpress
• legacy proofpress@next capsules remain readable and upgrade safely to latest
• Markdown anchors preserve wrapped, adjacent, and nested lists in GitHub rendering
• the Proofpress Action fails on real verification errors and falls back to the job summary when fork PRs cannot write comments
• stable npm releases are restricted to main + latest; prereleases use next
• CI covers Python 3.11/3.14 and Node 22/24
• privacy language distinguishes inconsistent tampering from self-consistent replacement, which requires an external trusted head or witness

Validation

• 44 Python tests and 3 npm tests pass
• clean npm tarball install and portable handoff pass
• all 18 tracked Markdown/HTML artifacts are portable, inspect cleanly, and advertise proofpress@latest
• GitHub's Markdown renderer preserves the repaired documentation and agent-workflow lists
• YAML, composite Action shell syntax, relative links, English-only source, and package contents pass final checks

Remaining launch gates

• the repository remains private; no visibility, merge, branch deletion, or release action is included here
• after merge: remove remote ledger/experimental refs, make the repository public, enable branch/security protections, then publish npm latest and confirm the v0.2.0 release and provenance
