chore: point everything at Vycari/maintainerd after the transfer

[allenhutchison]

The repo now lives at Vycari/maintainerd. GitHub redirects the old slug, so nothing was broken — but every install command and metadata URL still named a location that is no longer canonical, and a redirect is a courtesy rather than a contract.

What changed

29 slug sites — the root README install command, all seven plugin READMEs (install command + "Source and issues"), and homepage/repository in all seven manifests.

marketplace.json owner → Vycari. The seven plugin author blocks deliberately stay Allen Hutchison: ownership transferred, authorship didn't. Those are different claims and only one of them moved.

Two stale examples, found while checking: the worked example config said allenhutchison/pepper, but pepper is Vycari/pepper per its own maintainerd.json. Fixed — along with the two illustrative slugs in config-schema.md, which would otherwise have contradicted the example file sitting right beside them.

Not in this PR

The two consuming repos still point extraKnownMarketplaces at the old slug:

• ~/src/pepper/.claude/settings.json
• ~/src/obsidian-gemini/.claude/settings.json

Both keep working via the redirect. They're separate repos with their own review flow, so they get their own PRs rather than riding along here.

Verification

Vendored copies regenerated and in sync; links resolve in both layouts; zero references to the old slug remain anywhere in the tree; author intact in 7/7 manifests. Manifests edited as targeted text replacements rather than a json.dumps round-trip — that's what mangled two em dashes back in #14.

Greptile Summary

Updates repository ownership references from allenhutchison to Vycari following the GitHub transfer.

• Changes marketplace ownership and canonical repository metadata across all seven plugin manifests.
• Updates installation commands and source links in the root and plugin READMEs.
• Synchronizes the canonical and vendored configuration examples with the transferred Vycari/pepper slug.

Confidence Score: 5/5

The PR appears safe to merge, with the ownership, metadata, documentation, and vendored examples updated consistently.

The changes are limited to canonical GitHub slugs and owner metadata, preserve plugin authorship, and introduce no identified behavioral, build, schema, or security failure.
