feat: add directory prompt on run and cloud mode gating

When clicking "Run (Local)" without a directory set:
- Tasks WITH repository_config: Prompt "Do you have it locally?"
  → "I have it locally" opens folder picker
  → "Clone for me" triggers clone flow with progress UI
- Tasks WITHOUT repository_config: Prompt "Select working directory"
  → Opens folder picker

Cloud mode changes:
- Disable Cloud mode toggle for tasks without repository_config
- Show tooltip: "Cloud mode requires a connected repository"

Technical changes:
- Updated runTask() in taskExecutionStore to prompt before showing error
- Integrated with existing clone flow and progress UI (PR #128)
- Persist selected directories via taskDirectoryStore (PR #130, #131)
- Removed noisy directory source badges (simplified UX)

This creates a frictionless flow where engineers can easily point to
existing repos or clone them on-demand, while still supporting
directory-only tasks for non-git workflows.
