/**
 * Jira tools — native pi tools over the tracker REST API
 * (Jira Server/DC, rest/api/2). Thin wrappers around lib/jira.ts.
 *
 * No MCP and no bash: these are first-class tools the agent can call directly.
 * URL comes from config/company.json; JIRA_TOKEN from the env.
 *
 * CONFIGURE: config/company.json → trackerUrl; env.sh → JIRA_TOKEN.
 * DISABLE: remove/rename this file from extensions/.
