Update repository links and site URLs after migration

[brunoborges]

The repository moved to brunoborges/javaevolved, but documentation, installation instructions, and generated pages still referenced its former location. GitHub Pages is configured for https://javaevolved.dev/, which is now used consistently for public website URLs.

Changes

• Update repository links, plugin metadata, marketplace commands, and clone-directory paths to the new repository.
• Replace the old website domain in templates, canonical and structured metadata, social sharing links, documentation, and SVG/PNG social-card branding.
• Include OG renderer sources in build triggers and matching build/deploy cache keys so cached JARs cannot retain the old branding.
• Remove the Discussions contact link, keeping Discussions disabled as requested.

Validation

• Merged the latest origin/main without conflicts.
• Rebuilt all locales and checked 1,952 generated pages for migrated URLs and valid structured metadata.
• Generated and checked 135 SVG/PNG social-card pairs; generated artifacts remain uncommitted.
• Passed 16 detector assertions, the detector CLI smoke check, Java 8 bytecode compatibility, and git diff --check.
• Full plugin validation has a pre-existing documentation-coverage failure for timer-task-to-scheduled-executor, reproduced with both pre-merge and updated detector JARs. Existing missing-translation warnings continue to fall back to English.
