Subject: [PATCH] ci(dependabot): group updates per ecosystem into a single PR
 (#288)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

All nine Dependabot ecosystems now batch their updates into one grouped PR each
(`groups: { <name>: { patterns: ["*"] } }`) instead of one PR per dependency.

A routine refresh previously fanned out into a dozen-plus PRs (the Maven batch
alone opened 12), each running the full nine-language CI matrix (~55 checks) and
clogging the runner queue ahead of release and feature runs. Grouping collapses
that to one PR per ecosystem.

Trade-off: a single broken update blocks its whole group until excluded — fine
for routine maintenance bumps. Security updates are unaffected (they are not
grouped and continue to arrive individually).
