Repo-aware triage of open Dependabot PRs. Applies this repo's hard-won dependency rules (the Expo-SDK-managed lockstep set, the TS6 / Vite8 holds, dev-only security transitives, the mobile-e2e cache interaction) to recommend merge / hold / close / escalate per PR. Use when a human says "triage the dependabot PRs" or "look at dependabot PR #NNN". Conservative by default: recommends, and only merges green minor/patch PRs when explicitly asked.
