Fix MCP dep tool parameter names to match CLI (issue_id/depends_on_id)

- Changed from confusing from_id/to_id to clear issue_id/depends_on_id
- Matches CLI convention: bd dep add [issue-id] [depends-on-id]
- Updated all tests and implementations
- Fixes GH #113 where Claude Code was creating dependencies backwards

Closes bd-58
