ci: dedup stuff in changelog

[opencode-agent]

The iteration code on lines 252-256 will work fine with a Set since both Array and Set are iterable with for...of. No changes needed there.

Summary of the fix:

The issue was in the getContributors function at script/changelog.ts:194. When a force push corrupts commit history, the GitHub comparison API can return duplicate commits with different SHA hashes but identical commit messages. The original code used an array (string[]) to store commit titles per contributor, which allowed duplicates.

The fix: Changed the data structure from Map<string, string[]> to Map<string, Set<string>> (line 199). Using a Set automatically deduplicates commit titles, so even if the same commit appears multiple times in the API response, it will only be listed once per contributor in the release notes.

Closes #8514

[opencode-agent]

The fix looks correct. Let me verify the changes:

1. Line 199: Map<string, Set<string>> - Using Set instead of array to store commit titles per contributor
2. Line 207: new Set() - Initializing with a Set instead of an array
3. Line 208: .add(title) - Using Set.add() instead of Array.push()

The iteration at lines 252-256 uses for...of which works with both Array and Set since both are iterable.

The fix is correct and complete. The PR properly addresses the issue where force pushes can cause the GitHub comparison API to return duplicate commits with different SHA hashes but identical messages. By using a Set instead of an array, duplicate commit titles are automatically deduplicated per contributor.

LGTM - This is a clean, minimal fix that solves the problem without changing the output format or requiring any additional changes to the iteration logic.
