Summary

Add a parsec ticket [ticket] command to view ticket details (title, status, assignee, description) directly from a worktree context. When run without arguments inside a worktree, it auto-resolves the bound ticket.

Proposed Behavior

# Auto-detect from current worktree
$ parsec ticket
CL-2283: Implement rate limiting for API endpoints
  Status: In Progress
  Assignee: eric.signal
  Priority: Medium

# Explicit ticket
$ parsec ticket CL-2283

# JSON output
$ parsec ticket --json

Scope

• Jira REST API: GET /rest/api/2/issue/{key}
• GitHub Issues API: GET /repos/{owner}/{repo}/issues/{number}
• GitLab Issues API: GET /api/v4/projects/{id}/issues/{iid}

Priority

High — most basic ticket integration, low implementation complexity
