Search Confluence for pages in the [SPACE_KEY] space that have not been updated in more than 90 days.

For each stale page, note:
- Page title
- Last modified date
- Last modified by
- How many days since last update
- Page URL

Group into:
- CRITICAL (>365 days stale): Likely outdated, may contain wrong information
- WARNING (180-365 days stale): Should be reviewed this quarter
- REVIEW (90-180 days stale): Check if still accurate

Include a total count and a recommendation for the top 5 pages most likely to cause problems if someone follows outdated instructions.
