upgrade-dependencies

Recipe for upgrading packages safely - inventory outdated and vulnerable dependencies, read changelogs, upgrade one at a time or grouped by ecosystem, keep the pnpm lockfile disciplined, work through a breaking-change checklist, run build, tests, and type-check, smoke test the runtime, triage security advisories, pin and plan rollback, plan major-version migrations, and record decisions. Names the skills to apply at each step, the exit check, and what to hand forward. Load when asked to update, bump, or upgrade dependencies, resolve audit findings, or migrate to a new major version.
