Subject: [PATCH] fix: Remove legacy categories.json creation to prevent
 netifyd crash
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Issue Identified:
- Netifyd 5.2.1 was crashing with JSON assertion error on startup
- Error: "Assertion failed: m_it.object_iterator != m_object->m_data.m_value.object->end()"
- Root cause: Legacy categories.json format incompatible with netifyd 5.2.1+

The Fix:
- Removed auto-creation of netify-categories.json from UCI defaults
- Let netifyd manage this file itself or operate without it
- Both approaches work correctly with netifyd 5.2.1

Technical Details:
The UCI defaults script was creating categories.json in v1.0 format:
```json
{
  "version": "1.0",
  "categories": []
}
```

This format is detected as "legacy" by netifyd 5.2.1, which then attempts
to parse it with newer code expecting a different structure. When accessing
JSON object iterators, the assertion fails because expected keys don't exist.

Solution: Don't create the file. Netifyd works perfectly without it and will
create its own if needed in the correct format for its version.

Verified Working:
- Netifyd now starts successfully
- 22 active flows captured on br-lan and br-wan
- Both interfaces online with 0% packet drops
- CPU utilization: 0.1%
- Memory: 14.5 MB
