Bug: `task update --project` fails for inbox tasks with JXA error -10000

[yy]

Summary

Moving an inbox task to a project via ofocus task update <id> --project <project> consistently fails with:

Error: JXA error: execution error: Error: Error: AppleEvent handler failed. (-10000)

Other updates on the same task (--flag, --note, --name) succeed, so the task reference resolves correctly. Only the --project assignment fails.

Reproduction

1. Create a new project inside an existing folder:

   ofocus project create "HUFL household data" --folder "Urban science"
   # → id: akTq1ik9d-S

2. Pick an inbox task id (e.g. pwyeARZ8Xyk) via ofocus inbox --json.
3. Try any of these — all fail with the same error:

   ofocus task update pwyeARZ8Xyk --project akTq1ik9d-S
   ofocus task update pwyeARZ8Xyk --project akTq1ik9
   ofocus task update pwyeARZ8Xyk --project "HUFL household data"

4. But these succeed on the same task:

   ofocus task update pwyeARZ8Xyk --flag          # Updated
   ofocus task update pwyeARZ8Xyk --note "..."    # Updated

The project itself is valid — ofocus project ls "Urban science" lists it.

Verified the task stays in the inbox (project: null) after each failed attempt.

Context

• macOS: 15.5 (Darwin 25.5.0)
• OmniFocus: 4 (current)
• Fresh project creation + inbox-task reassignment. The project was created in the same session a few seconds prior.

Likely cause

The current JXA path (src/ofocus/commands/task.py lines 180–192) uses:

projLookup.match.tasks.push(task);

to move the task. With OmniFocus 4's JXA surface, .tasks.push() on a project has been flaky for inbox-originated tasks — -10000 is the generic "AppleEvent handler failed" and is commonly what OF returns when the sender/receiver container relationship can't be resolved for inbox tasks specifically.

Possible alternatives worth trying:

• app.moveTasks([task], {to: projLookup.match.tasks.beginning}) (or .ending)
• Setting task.assignedContainer = projLookup.match then task.inInbox = false
• app.move(task, {to: projLookup.match})

moveTasks is generally the documented way to reassign and seems to work for inbox → project reliably.

Workaround

Drag the task in the OmniFocus UI.
