Counts issues matching a JQL query.
Jira Data Center does not expose a dedicated count endpoint; this uses
POST /rest/api/latest/search with maxResults: 0.
Counts a list of values for one JQL field.
Counts lightweight contribution dimensions for one or more users.
updated uses Jira's updatedBy() JQL function. worklogIssues counts
issues with worklogs by the user, not individual worklog rows.
Lightweight Jira metrics derived from public Jira Data Center REST/JQL.
