Bug: Pagination message appended to JSON output breaks parsing

[rianjs]

Description

When using --output json with commands that support pagination (like page list), the pagination message "(showing first N results, use --limit to see more)" is appended after the JSON array, making the output invalid JSON.

Steps to Reproduce

cfl page list -s myspace --limit 3 --output json | jq .

Expected Result

Pure JSON output that can be parsed by jq:

[
  {"id": "123", "status": "current", "title": "Page 1", "version": "v1"},
  {"id": "456", "status": "current", "title": "Page 2", "version": "v1"}
]

Actual Result

[
  {"id": "123", "status": "current", "title": "Page 1", "version": "v1"},
  {"id": "456", "status": "current", "title": "Page 2", "version": "v1"}
]

(showing first 3 results, use --limit to see more)

jq fails to parse with: parse error: Invalid numeric literal

Suggested Fix

The pagination message should:

1. Not be printed when --output json is used, OR
2. Be printed to stderr instead of stdout

Environment

• cfl version: v0.2.0-21-g3fe51c4
• Found during integration testing
