Deploy releases on tag push, snapshots on branch push

bp-alex · bp-alex · commit cc2f24a40547 · 2026-02-06T09:45:32.000+11:00
Prevents double deployment during release:prepare by checking
POM version before deploying. Branch pushes only deploy if
version contains -SNAPSHOT; tag pushes only deploy if it does not.
