Fixes#363
## Changes
Created formulas/run-gardener.toml with 7 steps: preflight (pull latest), agents-update (AGENTS.md watermark check), stale-pr-cleanup (ping/close inactive PRs), dust-bundling (group trivial issues into bundles of 3+), ci-health (detect systemic CI failures), blocked-review (triage blocked issues per #352), and commit-and-pr (single commit with all file changes). No memory, no journal. All git writes collected in the final commit-and-pr step; API calls happen during the run. Steps follow the established formula TOML format with needs dependencies.
