Summary

The CmuxNext test package does not compile on feat-cmux-next:

Tests/CmuxNextAgentPaneTests/ChatDraftAttachmentsTests.swift:153:47: error: type 'Data' has no member 'init(base64Encoded:)'
Tests/CmuxNextAgentPaneTests/ChatDraftAttachmentsTests.swift:153:34: error: generic parameter 'E' could not be inferred

0b1a93e (#23394) passed Data.init(base64Encoded:) as a function reference. That form does not resolve because the initializer has a defaulted options: parameter. This PR uses the closure the file's other two checks already use: { Data(base64Encoded: $0) }.

Testing

cmux-ci run --class light --script scripts/ci/package-test-lane.sh --arg=suite --arg=Packages/macOS/CmuxNext --arg=<suite>:

• Base: the build fails with the errors above (aws-m4pro-3, step baafb50164f4df494cd93e04, a run at base f7a4033 that includes 0b1a93e).
• Head: ChatDraftAttachmentsTests, results in a comment below.

Observed / Not run

• Observed: the compile failure above on the fleet.
• Not run: nothing else; this changes one line in a test.

Summary by cubic

Fixes the CmuxNext test package failing to compile on feat-cmux-next.

ChatDraftAttachmentsTests passed Data.init(base64Encoded:) as a function reference, which doesn't resolve because the initializer has a defaulted options: parameter. Replaced it with the { Data(base64Encoded: $0) } closure the file's other checks already use.

^{Written for commit 6200483. Summary will update on new commits.}

Not verified: macOS jobs did not run: compile and app tests were skipped on 6200483734; ci-status is green without them.

CI passes on 6200483734 (run 39607592783 attempt 1).
macOS jobs did not run: compile and app tests were skipped: Fast static checks skipped (the macos job needs both to succeed). Re-run CI once they pass, before merging.

Written by scripts/ci/classify_failures.py (ci-failure-attribution.yml); signatures are its SIGNATURES table. A machine verdict is the runner's fault, not this PR's; yours means the failing file is one this PR changes, also red on main that main's latest full suite fails the same way, seen on other PRs that it failed on another pull request's run lately.

red: cmux-next checks (god files, concurrency, crash safety, l10n); base red: the same failure on the base c72fb36; does not block
