chore: union-merge DECISIONS.md to stop phantom-green conflicting PRs (#1351)

Every concurrent PR appends to DECISIONS.md, so any two of them conflict
at EOF. The real damage is not the conflict: GitHub runs no Actions on a
conflicting PR, so `gh pr checks` shows a short all-pass list that reads
as green when the test suite never ran. Union merge keeps both sides,
which is the correct semantics for an append-only log with no ordering
contract beyond the date prefix.
