--task is only supported for mission mark/rerun.

Error message

--task is only supported for mission mark/rerun.

What it means

Post-parse validation: a --task <id> was supplied but the action is neither mark nor rerun. Only those two actions operate on a single task by id.

Solutions

1. Remove --task for run/status/resume actions
2. Use `mission rerun <file> --task <id>` to re-execute one task
3. Use `mission mark <file> --task <id> --status ...` to update task status

Example fix

# before
mission run mission.md --task t1
# after
mission rerun mission.md --task t1

const hasTask = args.includes('--task') || args.some(a => a.startsWith('--task='));
if (hasTask && action !== 'mark' && action !== 'rerun') failEarly();

When it happens

Trigger: `mission run m.md --task t1` or `mission status m.md --task t1`.

Common situations: Assuming --task scopes a run to one task; migrating a mark/rerun invocation to another action but keeping the flag.
