v0.20.0 - Phase 2 Ecosystem Baseline

v0.20.0 - Phase 2 Ecosystem Baseline

Added

• Phase 2 ecosystem baseline documentation for RFCs, Atlas, governance, independent implementation, and application-layer adoption.
• Provenance documentation connecting the 2017 enterprise trust pattern to the current Genesis Mesh protocol and ecosystem baseline.
• Development documentation for Atlas, governance baseline, and the RFC program.

Changed

• Updated roadmap and development history to make the Phase 2 transition explicit after v0.19.0 operator continuity.
• Replaced the Windows-blocked large-file pre-push hook with a local stdlib hook.
• Restricted mutating formatting hooks to pre-commit so pre-push validation does not rewrite dirty docs.
• Bumped package metadata to 0.20.0.

Verified

• 297 pytest tests passed.
• Mypy, compileall, Sphinx docs, pre-commit, full pre-push hooks, and package build passed.
