[Feature]: Start mobile New Task in the most recently active project #5785

Before submitting

• I searched existing issues and did not find a duplicate.
• I am describing a concrete problem or use case.

Area

apps/mobile new-task flow.

Problem or use case

Opening New Task always begins at the project picker even when one project was used moments ago. Repeatedly creating tasks in the same project requires selecting that project each time.

Proposed solution

When New Task opens and there is a valid recently active project, start on that project composer. Keep the existing back action so the user can return to the project picker, and fall back to the picker when no recent project is available.

Why this matters

It removes a repetitive navigation step from the common case while preserving explicit project selection.

Smallest useful scope

Use the existing recent-project ordering already available to the mobile client. Do not persist a new preference or change project sorting. Apply the default only when starting a fresh new-task flow.

Alternatives considered

Persisting a separate default-project preference adds settings and state. Always showing the picker is predictable but slower for repeated work.

Risks or tradeoffs

Automatic navigation can surprise users who expect the picker. The selected project must still exist in the active environment, and back navigation must remain obvious and reliable.

Contribution

• I would be open to helping implement this.
