Bug: Permission Error on /app/data/bundles/skills when running via Docker on Windows

[Riseonelimit]

Describe the bug
Running docker compose up --build -d on Windows (Docker Desktop) causes the API container to crash on startup with a PermissionError: [Errno 13] Permission denied: '/app/data/bundles/skills' during the seed script. The container enters a restart loop and never becomes healthy.

Error

api-1  | Seeding skills...
api-1  | Traceback (most recent call last):
api-1  |   File "/app/scripts/seed_data.py", line 84, in seed_skill
api-1  |     storage_key, checksum = ensure_bundle(slug, full_md)
api-1  |   File "/app/scripts/seed_data.py", line 41, in ensure_bundle
api-1  |     bundle_path.parent.mkdir(parents=True, exist_ok=True)
api-1  |   File "/usr/local/lib/python3.12/pathlib.py", line 1311, in mkdir
api-1  |     os.mkdir(self, mode)
api-1  | PermissionError: [Errno 13] Permission denied: '/app/data/bundles/skills'

Root Cause
On Windows + Docker Desktop, the /app/data volume is mounted with permissions that don't allow the non-root container user to create directories. The seed script tries to create /app/data/bundles/skills/<slug>/ but is denied.

To Reproduce

1. Clone the repo on Windows
2. Run docker compose up --build -d
3. Check docker compose logs api — PermissionError on seed step
4. docker compose ps shows api container in restart loop

Workaround
Create a docker-compose.override.yml in the project root:

services:
  api:
    user: root
  mcp:
    user: root

Then run docker compose down -v && docker compose up --build -d.

Expected behavior
The API container should start successfully on Windows without requiring a manual override file.
