Summary

Add ability to post comments on tickets from the terminal, with automatic context like PR links and commit summaries.

Proposed Behavior

# Manual comment
$ parsec ticket --comment "Implemented with connection pooling approach"

# Auto-comment on ship (opt-in config)
$ parsec ship CL-2283
  ✓ PR: https://github.com/org/repo/pull/42
  ✓ Comment posted to CL-2283

[tracker]
comment_on_ship = true  # Auto-post PR link as comment

Scope

• Jira: POST /rest/api/2/issue/{key}/comment
• GitHub: POST /repos/{owner}/{repo}/issues/{number}/comments
• GitLab: POST /api/v4/projects/{id}/issues/{iid}/notes

Priority

Medium — nice complement to auto-transitions
