docs(agents): drop contributor PR rules from the agent brief

[pbean]

AGENTS.md carried CONTRIBUTING.md's contributor workflow as binding on agent sessions. Applied to maintainer work — where one task routinely surfaces several related fixes — the PR size caps and one-logical-change rule split single tasks across many PRs, multiplying review load rather than reducing it. CONTRIBUTING.md is unchanged and still governs outside contributors.

Removed

• "[CONTRIBUTING.md] is binding" and everything it pulled in: conventional commits (subject < 72 chars), PRs 200–400 LOC ideal / 800 max, one logical change, feature-sized work needs maintainer confirmation first
• "Open PRs ready for review, never draft"
• The ## Git & PRs heading, now ## Repo hygiene
• In the intro: "PRs that move orchestration into an LLM are rejected ([CONTRIBUTING.md])" → "Never move orchestration into an LLM"

The no-LLM-in-the-control-loop invariant is untouched — only its PR-rejection framing went.

Kept

The three bullets that are hygiene, not PR bureaucracy: CHANGELOG style, never commit session notes or run artifacts, and review non-convergence → escalate rather than grind.

Notes

Nothing enforced the removed conventions mechanically — no commitlint, no release-please, no installed git hook — so this is a docs-only change with no tooling impact. CONTRIBUTING.md, README.md, and docs/README.md still document the contributor guidelines unchanged.

Poem

A bunny hops through guidance bright,
Trims one sentence, shifts a title right.
“Repo hygiene,” the pages say,
While steady rules remain in play.
Hop, hop—clean words lead the way!
