Summary

Closes #94

• Expands tools/jtk/integration-tests.md from automation-only (~218 lines) to full CLI coverage (~692 lines)
• Covers all 12 top-level commands and 39 subcommands with ~180 test cases
• Modeled after cfl's integration-tests.md

New sections added

• Init, Config (show/test/clear), Me
• Issues (list/get/create/update/delete/assign/search/fields/field-options/types/move/move-status)
• Transitions (list/do)
• Comments (list/add/delete)
• Attachments (list/add/get/delete)
• Boards (list/get)
• Sprints (list/current/issues/add)
• Users (search)
• Shell Completion
• End-to-end workflows (issue lifecycle, sprint workflow)
• Command aliases verification
• Global flags (--no-color, --verbose, output formats)

Existing automation section

• Preserved and updated for UUID identifiers (from PR fix(jtk): align automation API parsing with Jira Cloud #87)

Test plan

• Review all command sections match actual CLI surface
• Verify test case format is consistent
• Spot-check a few commands with --help to confirm flag names
