Release v6.2.0

Changed

• Providers/Configuring is documented as deliberately excluded from the flat barrel: it declares commands with the same names as those in Adding, Reconfiguring, Removing and Renaming, so exporting both is ambiguous. Import it by path.

Fixed

• Twenty-eight generated proxy folders were unreachable from @cratis/ai. Agents, skills, provider pools, model discovery, tier mapping, Codex, Copilot, rate limiting and usage snapshots all generate proxies, but the package root's hand-maintained barrel had no export line for them, so importing any of them failed as a missing export rather than as a build error.
