`bm doctor` false failure when `project_root` is configured

[bengreeno]

Environment:

• Basic Memory 0.20.2
• Docker deployment
• managed project root enabled (/app/data)

Command:

• bm doctor

Observed behavior:

• The doctor command creates a temp-named project successfully
• Then it fails with:
  ValueError: API note file missing: doctor/Doctor API Note.md

However, the note is actually created on disk under the managed project root, for example:

• /app/data/doctor-7467a76f/doctor/Doctor API Note.md

So this appears to be a false failure rather than an actual write failure.

Likely cause:

• cli/commands/doctor.py creates the project with path=str(temp_path)
• later it checks for the created note under that same temp_path
• when project_root is configured, project creation ignores the requested path and resolves the project under project_root/<sanitized-project-name>
• as a result, doctor checks the wrong filesystem path and fails

Suggested fix:

• after project creation, use the actual resolved project path returned by the project service/API instead of assuming the requested temp path is the project location

Additional note:

• after the main failure, a background task logs a noisy CancelledError, but that looks secondary to the path-assumption bug above
