Ongoing community management, and new adopter onboarding

Updated project documentation. Online presence and in-person events. Outreach for integration and adoption in other FOSS projects. Enrollment of new contributors and corporate sponsors.

The issue names no files, tests, or entry points, so begin by breaking the work into its stated areas: documentation, online and in-person events, FOSS-project outreach, contributor enrollment, and sponsor enrollment. Done would require clear outcomes for each area, but the issue does not define those outcomes or how to verify them.
