docs(agents): remove manual coderabbit review trigger

[zgeoff]

Description

Reverts #931. CodeRabbit auto-review is enabled again (paid), so the manual @coderabbitai review trigger is no longer needed.

• Drops the trigger step from the build-feature workflow.
• Restores the Review bots guidance in AGENTS.md/agents/project.md to describe both bots as auto-reviewing.

Testing

• bun run typecheck passes
• bun run test passes
• bun run lint passes
• New tests added for new functionality

📝 Walkthrough

Walkthrough

The PR removes manual CodeRabbit review triggers from the workflow and updates repository guidance. CodeRabbit and cubic are described as automatic reviewers. Bot behavior changes must use configuration edits, and re-reviews require explicit requests.

Changes

Review bot guidance

Layer / File(s)	Summary
Automatic review and re-review rules AGENTS.md, agents/project.md, .claude/workflows/build-feature.js	The workflow no longer publishes a manual CodeRabbit review request. Repository guidance states that CodeRabbit and cubic review every PR, uses root configuration files, requires configuration edits for behavior corrections, and permits re-reviews only when explicitly requested.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🔵 Low · up to 6b8ac

The PR restores automatic-review guidance, but the wording includes draft PRs even though they are skipped; this could mildly mislead contributors about review coverage. The change is mergeable with explicit owner follow-up to clarify the documentation.
