docs(wiki): refresh repository article facts

[devswha]

Summary

• Refresh sourced wiki article timestamps and current release facts for patina, oh-my-codex, oh-my-claudecode, oh-my-openagent, gajae-code, and lazycodex.
• Update oh-my-codex, oh-my-claudecode, and oh-my-openagent homepage links from GitHub repository metadata.
• Keep the upstream article source-term test aligned with the refreshed oh-my-codex version evidence.

Evidence / sources checked

• gh repo view metadata for devswha/patina, Yeachan-Heo/oh-my-codex, Yeachan-Heo/oh-my-claudecode, code-yeongyu/oh-my-openagent, Yeachan-Heo/gajae-code, and code-yeongyu/lazycodex.
• GitHub releases for the covered repositories, including patina v4.1.0, oh-my-codex v0.18.17, oh-my-claudecode v4.15.1, oh-my-openagent v4.15.1, gajae-code v0.7.10, and lazycodex v4.15.1.
• Recent commits for the covered repositories via gh api repos/<owner>/<repo>/commits?per_page=5.
• GitHub Search API queries for AI-agent, developer-tool, documentation/wiki, and Codex CLI repositories. No new trending article was added because the results did not beat the current relevance threshold without adding churn.

Test results

• npm install completed for local dependency setup.
• npm test -- --run passed: 10 files / 65 tests.
• npm run typecheck passed.
• npm run build passed.

Merge is left to devswha.
