Problem

On Windows, netclaw init → Full reset fails with:

Reset failed: The process cannot access the file 'daemon-2026-06-26.log' because it is being used by another process.

The daemon netclawd holds the log file handle open, and Directory.Delete(path, recursive: true) aborts on the first locked file. The operator gets stuck on a confirmation screen with no way forward.

Fix

1. Stop the daemon before deletion

Inject DaemonManager into InitExistingInstallViewModel and call StopAsync('factory-reset') before any Directory.Delete() calls. This releases the file handles so Windows lets the deletion proceed.

Stop is best-effort — if the daemon isn't running or is externally managed (Docker container supervisor), it's silently ignored.

2. Show a progress screen with staggered checkmarks

Instead of confirming → instant failure, the operator now sees a dedicated progress screen:

┌─ Netclaw Setup ──────────────────────────────────────────────────┐
│                                                                  │

│   Stopping daemon…                                               │
│   Deleting data…      ✓ Daemon stopped                           │
│                       ✓ Data purged                              │
│                       ✓ Purge complete                           │
│                                                                  │
│   [Ctrl+Q] Quit                                                  │
└──────────────────────────────────────────────────────────────────┘

Each step fades in as it completes — the current step gets a spinning dots glyph, completed steps get a green checkmark, pending steps are dimmed. After purge completes there's a brief 600ms pause so the user sees the ✓, then the wizard launches automatically.

Key properties:

• Non-interactive: Once started, the operator can't interrupt the flow (Escape is a no-op during progress). Only Ctrl+Q exits.
• Best-effort daemon stop: If StopAsync throws (not running, external supervisor), the delete still proceeds.
• Same confirmation flow: The double-confirm screen is unchanged — operator still sees the warning and must click 'Yes' twice.

Files changed

• src/Netclaw.Cli/Tui/InitExistingInstallViewModel.cs — Added DaemonManager dependency, Progress phase, RunResetAsync() lifecycle, and progress-state properties
• src/Netclaw.Cli/Tui/InitExistingInstallPage.cs — Added BuildProgressScreen() with staggered checkmarks and spinner, updated key bindings for progress phase
• src/Netclaw.Cli.Tests/Tui/InitExistingInstallViewModelTests.cs — Added FakeSupervisor inner class and wired it into the Create() factory to satisfy the new constructor signature
