## Problem

Namespace owners want to control:
- Maximum nesting depth for replies (currently unlimited)
- The depth at which a "load more" button appears instead of inline display

## Proposed Implementation

1. Add namespace columns: `max_nesting_depth` (default NULL = unlimited), `collapse_depth` (default NULL = never collapse)
2. Add fields to namespace settings
3. Enforce max depth in reply views (both web and API)
4. Add collapse logic in templates

## Files

- `remarkbox/models/namespace.py` — add columns
- Alembic migration
- `remarkbox/templates/namespace-settings.j2` — add fields
- `remarkbox/views/reply_node.py` — enforce max depth
- `remarkbox/api/views.py` — enforce max depth on API reply
- `remarkbox/templates/show-node.j2` — collapse at depth threshold

## Acceptance Criteria

- [x] Namespace owners can set max nesting depth
- [x] Replies beyond max depth are rejected
- [x] Deep threads collapse with a "load more" button
