ci(release): run on every push to main

[vklimontovich]

Trigger release.yml on every push to main, not just manual dispatch. Existing
tag scheme (1.${COMMIT_COUNT}.${DATE}) already produces a fresh tag per commit
so no other change is needed. workflow_dispatch kept for manual re-runs.

Branch rulesets / auto-merge config is applied once locally, not via this repo.
