chore(renovate): fix lockfile-regen OOM blocking grouped dep PRs (#869) (#872)

The single `group:allNonMajor` group updated every dependency in one PR,
so Renovate's `renovate/artifacts` step regenerated the entire ~1.1MB
lockfile across all workspace manifests in a single pnpm pass — with
`pnpmDedupe` on top — and OOM'd on the heap limit (e.g. #719). The
lockfile then never updated and every `--frozen-lockfile` check went red.

- Drop `group:allNonMajor` in favor of smaller per-ecosystem groups
  (markdown/unified, ai provider sdks, build & test tooling, lint &
  format, framework ecosystems, @types, tailwind). A catch-all keeps the
  remainder bundled so we don't regress to one-PR-per-dep. Each PR now
  touches far fewer manifests, shrinking each lockfile pass.
- Drop `pnpmDedupe` from postUpdateOptions — the full-lockfile dedupe
  pass was the main memory driver.
- Add `minimumReleaseAge: "1 day"` to match pnpm's `minimumReleaseAge:
  1440` (minutes) in pnpm-workspace.yaml, so Renovate doesn't propose
  versions pnpm will refuse to install.

Note: raising the runner heap (NODE_OPTIONS=--max-old-space-size=8192)
must be set in the Mend hosted env — it can't live in renovate.json.
