Operators asked for easier branch/PR automation discovery from the default status/help surface. This adds a dedicated AGENT BOT section to both rich and plain output and locks it with install tests.

Constraint: Keep existing command catalog output and formatting stable

Rejected: Hide these commands under docs-only guidance | users requested in-CLI discoverability

Confidence: high

Scope-risk: narrow

Reversibility: clean

Directive: Keep AGENT BOT command docs in sync with review-bot-watch behavior changes

Tested: node --check bin/multiagent-safety.js

Tested: node --test --test-name-pattern 'default invocation runs non-mutating status output' test/install.test.js

Not-tested: full node --test test/*.test.js suite
