Summary

Base red on feat-cmux-next: cmux-tui does not compile. crates/acpmux/src/hub/bg_tasks.rs:160: cannot find value result_line in this scope.

Cause: a semantic merge of two PRs. #33347 (06fa0ed) added a result_line parameter to Hub::bg_start and put it into the task Spec. #33779 and #33982 had moved the body of bg_start into bg_start_with_id, which has no result_line. Each PR compiled alone. Together they do not.

Fix: bg_start_with_id takes result_line and bg_start passes it through. The workflow's machine task (workflow_activity.rs, the only other caller) passes false, so its behavior stays as before #33347.

Testing

• Compile-check job acbcf1a8e7a776abfb0b4450 at b19fc01: CmuxNext passed, app passed, cmux-tui passed.
• On feat (compile-check job 501d7bf473dfd6ad57c36281): cmux-tui failed with the error above.

Observed / Not run

• Observed: the compile checks above.
• Not run: the acpmux test suite (cargo test); the change only threads a flag through one function.

Summary by cubic

Fixes a compile error in cmux-tui caused by a semantic merge of two PRs: one added a result_line parameter to bg_start, and another moved the body into bg_start_with_id, which lacks that parameter.

bg_start_with_id now takes result_line and bg_start passes it through. The workflow's machine task passes false, so its behavior is unchanged.

Duplicate of #34053 (opened 2.5 min earlier, byte-identical diff, already has a SHIP at its head). My compile-check of the same change, job acbcf1a8e7a776abfb0b4450 at b19fc01: CmuxNext, app and cmux-tui passed. Closing this one so only #34053 lands.
