chore(config): enable pr-agent in the review pipeline, drop retired gemini

[cuioss-oliver]

One-line follow-up to #104. The pilot added the reviewer workflow but left enabled_bots untouched, so PR-Agent reviews would have been posted and never ingested into the findings pipeline.

- "enabled_bots": "coderabbit,sourcery,gemini"
+ "enabled_bots": "coderabbit,sourcery,pr-agent"

Gemini goes in the same edit: its consumer tier was retired 2026-07-17, so that entry only made finalize wait for a bot that can never post. Net bot count is unchanged, so the wait budget doesn't grow. The standards/gemini.md registry doc stays, so a historical Gemini comment still classifies correctly.

Now matches plan-marshall and TokenSheriff.

Labelled skip-bot-review — no reviewer value in a one-line config change.
