jira-commands

Update a Jira issue using jirac.

Steps:

1. Check that jirac is available by running jirac --version. If it is missing, tell the user to install it with cargo install jira-commands.
2. Extract the issue key and requested changes.
3. Map the request to supported flags:
4. --summary, --assignee (email or "me"), --priority
5. --labels <LABEL,...>, --components <NAME,...>, --fix-versions <VERSION,...>
6. --parent <ISSUE-KEY> to re-parent an issue
7. --description-file <FILE> (Markdown input)
8. --field <ID=VALUE> for custom fields (repeatable, e.g. --field customfield_10016=5)
9. Run jirac issue update <ISSUE-KEY> ... with only the requested fields.
10. If custom field IDs are unclear, run jirac issue fields -p <PROJECT> --issue-type '<TYPE>' first.
11. Confirm the update result clearly.

Examples:

• "update PROJ-123 summary to fix OAuth callback" → jirac issue update PROJ-123 --summary 'fix OAuth callback'
• "set PROJ-123 priority to High and assign to me" → jirac issue update PROJ-123 --priority High --assignee me
• "add labels backend,api to PROJ-123" → jirac issue update PROJ-123 --labels backend,api
• "set fix version to v2.0 on PROJ-123" → jirac issue update PROJ-123 --fix-versions v2.0
• "set story points to 8 on PROJ-123" → jirac issue update PROJ-123 --field story_points=8
