markdownlint-triagelisted

# Markdownlint Triage Turn Markdownlint diagnostics into a rule summary and a bounded cleanup. First-time trunk integration, including the Prettier-compatible Markdownlint baseline it seeds, belongs to `setup-trunk`. Trunk cache, download, or runtime failures are a different job and out of scope here. Requests to summarize or recommend settings are read-only. Change rules or documents only within the requested scope. ## Inspect the Active Configuration Verify the absolute repository root and account before inspecting its Git state. Read repository instructions, the selected runner configuration, and representative reported lines. Identify generated files and archives that require exact source preservation. Identify mirrored copies of the same document, such as per-profile duplicates: assign both copies to one worker and compare the pairs after repair. Do not transfer settings or results from another repository merely because its rule counts look similar. `markdownlint-summary` is on PATH whenever this plugin is enabled. It selects `markdownlint` on PATH, then `trunk`. It downloads nothing: a checkout's own `.npmrc` can point an auto-installed package at a registry the checkout controls, so the helper never runs `npx`. It requires Bash, awk, and standard shell utilities. A selected runner failure does not trigger another runner. Each runner uses its own configuration, ignore rules, and installed version. Running Trunk executes the checkout's own `.trunk/trunk.yaml` definit
