The root .gitattributes carries a stale duplicate rule:

.squad/decisions/decisions.md merge=union

The correct rule, .squad/decisions.md merge=union, sits at the top of the same file and has been there since commit 115fc04. The decisions/decisions.md path is not a real Squad state file (the decisions log lives at .squad/decisions.md), so the stale line matches nothing and only misleads readers. It was the source of confusion reported in #2378.

This PR removes only that one line. The correct .squad/decisions.md merge=union rule is unchanged.

Verification:

• git diff shows exactly one deleted line in .gitattributes, no additions.
• git grep "decisions/decisions.md" finds no other references in the repo, including test/, scripts/, docs, and templates.
• .gitattributes is not listed in any package files array, so no changeset is needed.

What changed in this PR

Removes an obsolete Git attributes rule to clarify which Squad decision log receives union-merge handling. This is configuration cleanup, not a fix for the state-MCP behavior reported in #2378.

Changes:

• Removes .squad/decisions/decisions.md merge=union.
• Preserves the correct .squad/decisions.md merge=union rule.
