docs: fix stale domain references in README

- "seven project domains" (contradicted "six") -> "a growing set"
- clarify the six canon charters are the founding domains; note the hub
  now tracks a larger live set (14 active) via list_domains()
- rename Foerster Capabilities -> Capabilities (live domain slug) in the
  dependency chain and domains table
