feat(catalog): list Site Crawl deployment SEO plugin

[dviejokfs]

Summary

List Site Crawl from its standalone public repository, gotempsh/temps-plugin-site-crawl, under SEO and automation. It finds broken internal routes and technical SEO issues and can crawl after successful deployments with the administrator-granted events_read permission.

Verification

• Registry validation: 13 tests passed; both listing records pass metadata validation.
• Plugin CI passed: typecheck, 44 tests including compiled process authentication/API/UI, native compilation, and reproducible embedded assets.
• GitHub catalog validation passed on commit 1ed9c8f: both plugin repositories install locked dependencies and compile with network disabled.
• Fixed the initial ENOSPC failure by raising bounded build /tmp from 128 MiB to 512 MiB in PR validation and catalog refresh; regression checks cover both paths.
• Local slot 29 is healthy and its real UI was exercised. CLI installation of Site Crawl was attempted with events_read, but the host build failed. Outbound GitHub requests from its Docker builder time out; installed-plugin runtime verification remains blocked by local Docker networking. The temporary CLI API key was deleted.

This adds the listing record only. The catalog becomes publicly discoverable after merge and the catalog refresh workflow; no production installation or merge is requested.
